I have heard this as well. heck, i have even said it. I have since came to the conclusion that for the most part when a ball doesn't seem to fit a bowlers style, that is just a very condition sensitive ball.
I had a ball, the Storm Trauma Response, that i really didn't like or use much. But i took it to a tourney and ended up using it, and it was awesome on that condition. I have never found a good condition for it since that tourney.
However, on the flip side, I had another ball that never seemed to work for me. I had it plugged and redrilled 3 or 4 times and never got a good reaction out of it. I gave it to a teammate that had a lot less hand than I do, and he loved it.
my personal conclusion, it is possible that a ball just isn't meant for your game but that is really the exception to the rule and rare.
