I (260 lbs.) started one of the early threads on the Canzo 29er and have been riding one for almost two years now without a single problem. It's a great bike at a great price and the rear end is less flexy than than my RIP9. The black '09 version due out now looks sweet. The Med. Canzo feels smaller than the Med. RIP9 for comparison. A TA fork as mentioned above and a bolt-on rear hub, along with the big 31.6 seatpost is a great set-up for a Clyde.
