Drill the Raptor 60 x 4 1/2 x 30. If you need a balance hole place it in the P2 position.
 
The Primal is a very smooth rolling piece of equipment so getting it to be angular isn't going to be easy esp. w/ your high rev rate. This piece helps the low to med. rev rates out there open up the back end of the lane b/c the cover has a higher Ra value. As a high rev player you'll come to appreciate this piece on tougher, spottier lane conditions where you need a predictable motion. My recommendation is to put the pin 5" from your PAP above the fingers if you want a quicker transition down lane. Kick the CG out enough that you can add an extra hole later, but not so much that it doesn't comply with the USBC. Somewhere in the ball park of 3/4 oz. of side weight would be ideal to start.
