Hey Rocker,
1) GP2 to handle more heavier oil than the Blue Heat
2) Arsenal Angular because it should offer you that skid/flip reaction in case the shot allows you to open it up some. I would've said the 5.0 but with the mb left of thumb, the ball is more controlled now and is a little close to the MM IMHO.
3) Xception to fill the gap between your MM and Desert
4) Heat to go in between the Xception and Desert also
With these 4 (and along with your other 4), you will at least have covered most of the various oil concentrations you may encounter with their surfaces alone. That's what I'm thinking bud....go whack'em ROCK!
