i have no experience with the fuji track, but it seems all right. if you can ride one and a pista, do. i think the fuji looks like crap, but hey, go with what feels right, then make it look right.
the pista's not bad for an entry level bike, but should you get hooked, and i think you will, you'll want to upgrade the parts, there's absolutely no doubt about that. at all.
EDIT: i ride a pista, and almost nothing is stock on it, and i got it that way...i can't speak for how good the stock parts are, but i haven't exactly heard glowing reviews. i can say, though that i'm damn glad it doesn't have stock parts, though, just from looking at fresh-off-the-shelf pistas.
