Hello everyone I have a question about drilling my new Xception. First let me tell you that I throw around 20 mph with very high revs. Stand on 30 to 35  roll over 15 slide out to 7 and in the 1,2 pocket. Thats with my Xtreme from storm specs. 3 1/2 pin. finger holes even with pin 1 1/2 away cg in palm of hand thumb next to RAD.I don't know the PAP.With this layout I get a very strong midlane reaction with nice backend. O.K back to the Xception I know its going to go long I just don't want to over power it .I'm looking for the strongest backend reaction I can get out of this ball. My local proshop drills balls great as far as fitting goes but layouts are another story!!Also I bowl on synthetic lanes with medium oil with medium carrydown.I hope thats enough info for someone to give me some ideas. Thanks

Hey lefty,

I think both Ex and I have had pretty good success with the Rev Lever core at these distances for most.  I also have mine at a 4 1/8pin by 4mb and it offers a fantastic backend reaction when my Rule starts to get a little too strong for the heads.

I'd suggest pushing your pin distance back some (to about 4.5-5 inches)compared to your Xtreme but you can keep the mb in relatively the same position for length and backend.  Hope this helps some...
