i think it 100 percent skill, balls do not make the bowler. for example there is a guy that bowls in my fall season with a mutant cell, carries like a 232 avg, he suitcases the ball on the 2 arrow and BAM every time, he tried bowling in the PBA experience league hasn't broke 100 yet. a good bowler should be able to roll any ball that fit his/her hand and make it strike. don't get me wrong i think the right gear makes it easier, and i know the ball can do work for you, but before that the bowler has to lay it down right and consistent or else the ball does not have the same outcome.
