Interchangeable Thumb

[mikenoodle]

I tried ITs this season and if you're considering Interchangable Thumbs, I have two words of advice:

Do it!!!

They create a consistent feeling from ball to ball and make ball changes during tournament or league play about changing balls and not how the thumb in ball X or Y feels.

I will NEVER drill another ball without ITs

I switched to the ITs grips last season. I borrowed someones ball he was selling and he has them. Threw a 279, bought that ball and a couple weeks later a 300. Then I started the process of switching over all my other balls to them. I try to keep at least 2 different sizes of thumb. I have even learned that if I am leaving corner pins a switch to a different size thumb will make all the difference.

Or you could do what I did and start learning to bowl without a thumb.

I've bowled thumbless and two-handed and neither were right for me. But at least I tried it. My thought was; how can you coach it if you don't at least try it?

I've never coached, but I first went to no thumb (two-handed) because I felt like trying it. I enjoy testing out various ways of throwing the ball, so this was one more to do. Since I did fairly well with it and it gave me a new way to play the lanes that I couldn't before, I kept up with it. At times when the oil pattern is sketchy, I'll go back to one hand for more consistency.

I currently have - I don't know what it's called - but the thumb is adjustable with a small screw, so you can tighten or loosen it by turning the screw. Would you suggest changing over to the ITs when I replace my balls? Is there any benefit with them over what I have now?

[mikenoodle]

the benefit is that you will have exactly the same feel from ball to ball with ITs because you have exactly the same thumbhole from ball to ball. It's not that it's adjustable, it's that it's consistent from ball to ball
