axis rotation/migration/tilt. Here with a 3 piece ball(little or no flare).On this type of ball(3piece polyester), the axis point stays in a very 'stable' position(the ball track does not flare or very minimal) but migrates to the left side as it transitions from a skid ,hook and roll. I'm throwing a 10 o'clock release(45 degree rotation perpendicular to the lane and approx. 13 degrees tilt upwards). As the ball rolls towards the pins, the bowler's preferred spin axis will migrate towards the left side of the ball along the migration plane, when it reaches the pins, the axis point almost disappears to the left side of the ball and the tilt of the axis also reaches 0 degree(a true foward roll). This happens because the ball ultimately wants to roll straight as it loses energy(side spin). On dry lanes the migration will happen sooner(sometimes at the arrows), and on very oily lanes the axis point may not even migrate at all(the axis point will stay at the same position from the point of release, and skid all the way to the pins).
whats the name of the ball?

ebonite lolipop drilled with axis balance. that means the smallest circle on the ball was placed on my preferred axis of rotation. this is so we can see the the lines stable as the ball rolls down the lane. this is my training ball for when I want to work on changing my tilt and rotation.
