 Okay I can't lie this is a very selfish experiment I currently game the stealth to HD I use that term lightly I do swap out for the tailor-made mini burner driver quite regularly but the new QI 10 max does interest me and it did perform incredibly well out on the course for a few rounds so I want to take a closer look at the numbers but we have to start here and find out why the 10k MOI is such a huge leap for tailor-made. You can clearly see they peaked at eight and a half thousand MOI and that is where my current driver sits as it being the most forgiving driver in tailor-made history until now so is this one giant step for mankind does 10k really matter is it simply a new buzzword to get fixated on within the world of driver technology does it represent true forgiveness for woeful swings and for me at least is it any better than the stealth to HD all will be revealed in today's video so the three factors for me to consider ball speed launch and spin but finally and maybe the most importantly one element we're going to attempt to measure today to decide if MOI is real so how did they achieve 10k and what's so different about this new driver well first of all the rear weight was 30 grams in the stealth and it's 32 gram in the qi 10 max and the heel weight has had a big move and there is also a significant shift in the amount of carbon in the crown 97% in the qi 10 max and 79% in the stealth too they've also removed a considerable amount of titanium from the stealth body and replaced it with carbon all to save and redistribute weight the shape is then very different and different for a reason it is 8 millimeters longer which means the 32 gram weight can be moved even further back than the position it was in the stealth too okay so that's first ball of the morning 149 smash factor which is the key bit in terms of efficiency 93 club head speed 12 launch 22 pk 26 spin 221 carry it's a real good first number I feel like that's the kind of swing how it hits off the first auto but it's off the first T at st Andrews or any golf course for that matter it's the one that like I said 93 I was topping out yesterday around in 97 so we're away down on full club head speed yet but I like to see what a club does in and around an area where I feel comfortable again what's interesting really good straight ball flight it's probably very similar it felt very similar anyway I feel like I'm finally in the middle of the club face so what we've got 226 carry slightly higher launch I'll carry on it in numbers with this that's exactly where I'd expect this to be and the key factor for me is that smash factor the other important bit right now we've got two balls down the middle of a fairly big fairway don't get me wrong so I'm going to carry on hitting this and then we'll switch this shaft into the older club their HD and just see what kind of difference it makes interesting bit there for me three from three almost identical in where they finished up on the fairway and not too dissimilar in every parameter that's what I'm looking for is consistency of performance that's what seems to be good about this year's drivers again not going to be too dissimilar they're on top of one another well it one more to give us a round number of that well at five and I don't really need to it anymore the only thing I'd like to do is be able to come back to this when I'm warmed up a little and maybe see what we can get out of it distance wise it's probably worth mentioning at this point as I switch into the exactly the same head nine degrees I have the shaft that I use is a good inch and a quarter realistically shorter than your regular driver shaft so this is 44 and a half inch shaft I switched into this over maybe almost two years ago with the original lineup of stealth just for control and trying to find the center of clubface the reason I'm pointing that out for anybody who's looking to do any sort of comparisons relative to other reviews that I've done we've got to bear that in mind because the likelihood is I'm not really going to get clubhead speed up to 97 mile an hour with this shorter shaft hopefully we can get up to sort of 95 95 in a bit maybe but it's a big consideration because obviously you know clubhead speed is then going to be relative to ball speed so important fact I mean it's interesting for me looking down I did like the little red accent that they added in stealth too and probably you know I prefer this at address I've got to say but then the whole red versus blue thing is an issue for me full stop so yeah I should order one of the bespoke ones that you can get in the red in the qi 10 it looks superb well that's you know again straight out of the blocks very very similar to the line in fact I've got three balls that I'm looking down to the right hand side three balls that are almost on top of one another where they finished on this big fairway and yeah again efficiency wise 148 1.48 that is a 180 spin low 221 carry launching 15.4 and a very straight ball flight yeah again just a little bit of movement from right to left not as central as those first two but what you'll see is the graphic that I'm looking at down the right hand side is we've got a lot of balls that are in identical position that 222 carry distance is something that we've been seeing that sort of low to mid 220 carry with a spinning around 2000 revs you know I mean it's we've picked up the clubhead speed a little bit and we're still remaining at a 1.49 smash factor which is incredibly efficient one final experiment we're just going to switch up to a full length 10 side blue 65 stiff which is again a shaft that is often fitted for me I'm going to try that in both heads and just see if we can creep up that clubhead speed just a little bit so we've got a comparison versus other drives that I've tested in that distance stakes at least today's video is sponsored by our friends at hot golf the online golf retailer for all major brands and if you want new golf gear then please support us by supporting them okay so this video on the last few have been all about sort of analyzing data whacking a lot of balls and just seeing if we can differentiate between these new and older clubs now don't forget this HD was eight and a half thousand in this MOI steak so you know it's it's it's up there how much does that leap really mean to that 10k model that's what I was trying to establish today and when it started off at the kind of 93 mile an hour clubhead speed I'm going to say performance was very very similar indeed I never spotted any real obvious issues the one thing I would say that with the HD I had the odd ball that would pop up to three and a half thousand revs on the spin and just float a little which can be dangerous but it was an odd ball there was more consistency of the max in terms of maintaining that spin number and if anything the odd ball with the max fell kind of quite low for me as well so there was variables in both the one thing just going back to the address position until I filmed them both afterwards because I've never told you that eight millimeters which doesn't seem a great deal but at address it is hugely different when they're side by side but I've got to say when I switched in and out the two I never really noticed just how big the max product was although I will go back to my initial comment where I do like the little red accent that was on the HD model and probably prefer it from the address position back to performance I then switched things up we changed shaft we went to the full length shaft that 10 side blue once again similarities but the gap started to widen slightly in that we were starting to see a slightly better performance or a slightly more consistent performance coming out that max product and this is where it got interesting for me because the final piece of the juicer that I alluded to in the introduction to this video was we were going to look at a piece of trackman data that might give us more clues as to what is going on in the forgiveness stakes and impact location is something we've looked at in the past and we've doubled that essentially it's where you're hitting the ball within the club face and just how consistent performance becomes when off-center strikes occur and that was really interesting and only at the very end when we started ramping things up a little and there was a number of shots that were very much off-center with both but the max dealt with them far better than the HD I wasn't honestly expecting to see that because up until then it remained fairly consistent but I've got to point out that when you were striking center of the club face center of the club face there was no great difference but when you were finding the center that's when you started to see the benefit of the max product now I started hitting more off-center with the longest shaft hence the reason I used the shorter shaft and it also started to occur when I swung a little bit quicker which is natural with the longest shaft now the other thing with swinging a little bit quicker is what I found with these reviews of late is these latest drives that have come out they're almost better suited or the better player is going to get more benefit out of them than the than the average Joe if you like because what I'm seeing is it's almost like these clubs although they're max by name they've been designed for where a better player can gain advantages of the forgiveness that was built into clubs that would naturally spin too high in the past if that makes sense so it's an odd one because you always associate max products with the sort of masses but I think you'll see more of these clubs and we already know I mean Colin Mora Kaur has gone for the max version which sort of reiterates the points so what you're getting is better players with faster swing speeds than me are going to gain more benefit because what they're not going to see in the past it had been a ballooning effect with a lot of high spin they're not necessarily seeing that where this combination of I don't know how they've managed to put all this things together I've explained what Taylor made us saying but I think they've just got a very good combination of maintaining a good launch fastball speeds from across the club face and a spin number that isn't ballooning too high I hope that all made sense it certainly did to me within the testing you should have seen some overlays of some shots that performed still incredibly well from off-center strikes with the max and fell off a little with the HD that's the kind of proof if you like I was looking for but look it goes without saying I said it in a previous video if I'm gaming the HD and that's where I'm at right now in a stealth 2 I'm happy this is a really really good golf club I've loved it it's very consistent and at my 93 mile an hour club head speed out on the course am I really going to see the gains that are possibly there in the qi 10 max I'm not so sure if I get out there and I start to like a little bit excited and confident and start to step on a few I want to sort of get up to that 96 97 mile an hour club head speed and I consider going back to a full length shaft am I going to see benefits from the qi 10 max I think yes is the answer to that question so as ever it really depends on what you are looking for from your driver and either way there are some incredible options out there right now the story is always the same what you do is if you're not looking for a driver you're happy what you've got in the bag then you don't need to throw any shade on any manufacturer that's trying to attempt to change things slightly you just crack on with the one you've got if however you want a bit of a change up then what you do is you go and get custom fit because it's essential you take your old driver you see how it performs and stacks up against a new driver if there's no difference you keep your money in your pocket but if there's gains that you recognize that might help you enjoy the game a bit more then and you can afford to do it then go ahead and do it it's as simple as that really anyway I hope that the information that you got in today's video was some way of a pointer to helping you differentiate between the two I think I've got my answers anyway right thanks for watching I'll see you all soon
