Answer
I would have 2 things checked that might be an issue.  Check your span and check your thumb pitch.  If either, or both, of those are off, you will have problems with holding on to the ball.

If your thumb changing sizes is and issue, and you dont like using thumb tape, look into the Turbo 2N1 Switch grip or the Vise IT system.  Both of these would allow you to change grips as your thumb goes up and down.  Keep in mind they are more expensive than tape.

Good luck,

One other thing, have someone take a look at your timing.  If your body is too far forward, it may cause you to drop the ball.  Also, if your foot gets to the foul line to far ahead of the ball, that may cause you to drop the ball as well.
