How to make sure a sleeping bag will keep you warm

[TIGDIF]

Hi, great vid and has narrowed my decision on a new sleeping bag to 2 of the same name (terra nova) but different ratings. The problem is this - one bag has a rating of 10 to 3 degrees (£197) and the other is 0 to -7 degrees (£325), I want to use it all year round really but will I get too hot in the more expensive one on warmer nights? or should I buy the cheaper one and just put more cloths on or use a cheap silver emergency safety blanket to put over the bag if the UK winter gets really cold?

@TIGDIF Over time all bags become less efficient, so it is best to start off with a slightly warmer bag. Also while you can add clothes to make a bag feel warmer, this can be uncomfortable and potentially it can reduce the efficiency of the bag because you may find that you have so many clothes on that you square the insulation in the sleeping bag and hence the bag is less able to keep you warm. If in doubt choose a warmer bag than you need and open the side zips when you overheat.
