Doug,
One thing: Don't forget your XP has the Fusion core, not the Diamond. Doesn't seem to be much difference but there is one.
I've just now started figuring out the XP after a few months of ownership and ended up bowling my highest series of the half with it Tuesday. I basically have to treat it like I used to throw my old Storm X-Factor when its cover was still fresh. The 900Global covers are much more angular than the Brunswick covers were, and for that reason I've started to sprinkle in some Visionary, Brunswick and older gear in order to get a different look.
Nicanor, I'll tell you about the Dynamo -- when I get one. (g) I'm going to get a Chainsaw next month and that will probably be it for me until summer leagues get here, and I want to try the Agent Orange first.
