I have the SSP, X Pearl, and the Boom. I also have a high track, with high revs and above average speed. I drilled the SSP pin above the ring finger and the CG kicked out a bit under my ring finger. I drilled my X Pearl pin above ring and CG stacked below. The SSP makes a harder move compared to the X and gets through the mid's better. The X Pearl get's through the heads very easily, but makes a earlier move with a much more controllable backend reaction. Both are great balls.
I drilled my Boom with the pin right of my ring finger and stacked the CG, a leverage drilling. It burned up way to early for me and kind of died on the backend. I recently dropped it off to be redrilled, similar to my X Pearl.
