Can get a great deal on a 2012 Giant XTC Composite 1
Carbon Frame
Fox Front Shock
Sram X7 2x10
Giant Wheels

Its a 22" frame, and I'm 6'8" / 275lbs. How's the fit with the XTC and big guys? There's no 22" Giants in town to try out. I rode a Kona Kahuna DL in a 22" and was happy with the fit. Also how is the XTC composite frame with big guys, I generally break aluminum frames down at that corner by the rear derrailleur just from pedalling, is carbon a good idea for me? Any help would be appreciated.
