I have 1.5" pins on both my pearl and solid Uraniums. On both balls, I have the pin below the ring finger and cg toward the center of grip (1:30 label drilling), no weight hole required.
The reaction is very smooth and predictable -- nice arch with some backend. I use this drill on most pin-in balls I have, regardless of company, because it works well.
On my pin-in Cranberry, I've also tried pin below the fingers on the center vertical line and the CG kicked to the right, but I haven't had as much success with that drill. However, it just could be me.
Good luck, and let us know what you go with.
