Try the DiMarzios first, then :)
Odds are you won't find the perfect combination on the first try, so why not start with the X2n & Ppro. If they don't work for you - pass 'em on and try something else. Swapping pickups is relatively easy and quick once you get the hang of it. I've tried numerous pickup combinations myself and sure enough will be doing so in the future (but first I'll try the Duncan Blackous Modular Preamp!).
