There was a good shortstop player in my home town that, like UWPoolGod, had short stubby fingers yet played with a 14mm shaft Joss West. He could barely get his fingers around the shaft but, it worked for him. Point being, try all sizes and find out what fits your game best. I, again like UWPoolGod, play with a 12.5mm shaft but I play golf on the snooker table with an 11.5mm.
