Grip strength?

Another thing about grip pressure relating to your fingers. Slightly more pressure on the ring finger will make the ball tend to roll up earlier and on the ring finger the ball will go longer and flip later. Still you don't want to put the claw on it, just slight increase in pressure so your release is still relaxed. You should really experiment in practice with that as well as moving your index and pinky around in your grip to see the different results. You may find that it will change your ball motion in a positive way.

Sorry it isn't what you meant but you did say thumb should be as loose as possible in the very first sentence so you can see how it could be misinterpreted from what you meant.

Because we aren't talking about fit, we're talking about grip pressure - and I stand by my statement. Thanks for commenting.
