Nice turkey, Ed!
What you actually want is a ball that fits your hand. The holes shouldn't be too tight or too loose, and you should be able to barely slip a pencil between your palm and the ball with your fingers in the ball. I actually use what they call a fingertip grip, where my fingers only go in to the first knuckle; I don't consider myself that strong, yet I can handle a 15 lb. ball w/ a free swing and w/o much grip pressure b/c the ball fits.
