The pin has no relevance in a pancake core, as far as I know.
It just holds the pancake in place while the ball is poured.
CG means everything. It is hard polyester. BUT you're not going to change a lot by moving the CG around.
If you want a polyester ball with a dynamic core, you need to get a Lane #1 XXXL or some older plastic ball made by Ebonite, like the Gemstone or the WereWolf or Wolf clear balls.
