I just finish a "Clyde" build of a Specialized Hardrock. So Far So good, but I only have a couple of hundred miles on it so far. Prior to that I was riding n 85 Raleigh Elkhorn (currently under maintenance).
Also I did get away with a well built (DT alpine spoke) 36 spoke rear wheel. The failure I encountered was then axle related (bent), after an incident relating to a large pothole (traffic avoidance). In that time period I was well over 400 lbs.
Your selections seem reasonable. Finding a bike that fits and adjusting/adapting it for comfort is a critical to the over all experience.
Hope you find the same success in cycling that I have.
