Yeah, I'm kind of going through the same thing now -- however I don't really have a line on a good deal like that. $600 is a lot of dough. I guess the XC is about a 1/2+ lb lighter on the frame, but also not as strong. I weigh 170, so I wouldn't worry myself; however if I weighted another 15 lbs or so, I'd probably steer clear of the xc. Anyhow -- pros and cons of each. Think the Classic is a little better technical trail bike, from what I can tell. Does one frame fit you better than the others? For me, I'm 6' but a very short torso, so the classic would fit better.
Anyone (including nacraman) have a line on a good deal for a blur classic they'd be willing to share? Most likely, size M. Please respond or e-mail me at averyall at yahoo dot com
