I bought a P1 (actually, a P2SL) over a P2(C) for a number of reasons.. Not the least of which was that I prefer aluminum to carbon (*Gasp!*). Yes, carbon rides nice, no argument there, but I'm perfectly comfortable on an AL bike. When I shipped and flew it, I never had to worry about a minor nick turning into a structural failure.

Now, if you feel like you're going to have "carbon envy" after buying the AL bike, then pull the trigger on the P2. Just know that the vast majority of riders (and a larger majority of triathletes) will never be held back by a P1.
