Does it affect shot consistency, flat strokes/serves and volleys?
I'm going to jump in here if you don't mind because our TW Professor is extremely busy testing new product.
There has been some discussion that smaller grips enable the player to use a little more wrist on their shots, and by doing so the player is able to generate bit more spin on their shots. This is a more modern discussion because classically players used larger grips to provide more wrist control and thus more control on their shots.
More modern players like Rafael Nadal have switched to smaller grips so that they can use more wrist in their shots. However, this is not a proven science, but simply more of an opinion or a theory.
Grip size ends up coming down to personal preference. The only way to find what works best for you is to try your different options yourself and see which one you like best.
