WaveMan, I'm about the same size as you, and I wouldn't look for a lot of life from that bike. I ride pretty aggressively, and I could see that folding under me after little more than a year. Not good enough, IMO.
Right now, I'm crutching along my old Jamis Dakar XLT, hoping it lasts until February, when I will build up a Santa Cruz Butcher, investing about $2K. If I do as well with the Cruz as the Dakar has been, I will be pleased. I don't own a car, so the bike gets a lot of time. Right now, I'm between 15K & 16K miles on the Dakar, and I was money ahead JUST ON GASOLINE 18 months ago!
