I don't want to say cgs don't matter, but for reaction, they really don't. All the length of a pin is for is the distance of the cg to the pin. And all the CG is for is the heaviest spot on the ball. It is only o make it easier to drill a ball and keep it legal. You can put what ever drilling on it, you might just have to have the fingers drilled to the core or a very large weight hole. Ball reaction comes from the pin and MB is relation to your PAP. Static weights have little to no effect on your ball reaction. So, as long as you don't mind a high weight hole, don't worry about pin distance, it has no effect on reaction once the ball is drilled.
