One reply asked how old I was, I am 68 and in fairly good health but overweight a bit (of course), knees not the best, and using a rather short approach. I have been bowling for over 40 years and still love the game. Although my mind still thinks like a 30 year old, my body says otherwise!! So I know I need to make changes to compensate for all this relative to equipment, basic mechanics etc. Thus the question about a ball with modest arc at lowers speed, one that I can control in my reduced capacity to fire hard and fast.
