I have a set of Flo 30 wheels.....28H x2 rear and 20H radial fronts that I started riding this winter at just around 250lbs. I have only maybe 400 miles on some very rough roads and I know I should trust them but somehow deep down I think I need more spokes, more rim, more tire. Thinking of taking this set on a 600K out of DC. The roads are so nice down there. Paved every year. What could go wrong? I have to fix a spoke? The wheels would probably save an hour compared to an unlikely 20 minute spoke repair.
