Someone PLEASE correct me if I am wrong.

A ball with a 1-2" pin compared to a 3-4" would tend to get into its roll earlier then a ball with a 3-4" pin. 3-4" pin balls are great for that big backend skid/flip reaction. (Asymetric balls will react differently as their Mass Bias are all slightly different from each other, my response is for Symetric balls)

As I understand it smaller pin to cg distances limit the drilling options as there are fewer ways to lay out the ball while still keeping it legal (I.E.  It's pretty tough to put the pin anywhere above the fingers cuz then the cg is just an inch or less from your fingers)

As a result most short pin-cg distance have to be drilled with the pin somewhere under the fingers and the cg fairly close to mid-grip.  People with shorter spans can get away with shorter distances, and a good driller can make some adjustment but you can expect some weightholes or insanely deeply drilled fingers and or thumbs.

Yeah. You know, I had a guy in Jackson county. He had a little drum circle in his backyard. It turned into a drum circle four miles in diameter. You get a few hippies playing drums and next thing you know, you got yourself a colony.
