Full roller?

well, i don't have a thumb hole. I bowl with no thumb.

Regardless if you have a thumb hole or not, the track in relation to your finger holes has apparently led this other bowler to believe that using a full roller layout may give you a better ball reaction. It's not a matter of making the ball hook more or less, but creating a reaction that works for you. Talk to your PSO and see what he/she thinks.
