I used to bowl until 12 years ago and came back this year. My old ball, which I gave away when I quit was drilled fingertip. I can't remember why I changed to that idea. Since coming back this year my new balls were drilled fingertip. My question is should I stick with them or change. I am more of a roller than a "cranker". I use a 14lb Hammer Pearl Vicious and find it anything but. I figure that I am the problem but at least my average is where it was before. The trouble is I want to improve and wonder if the grip could be part of the problem.
