Have gotten used to clipless over the last few years, starting at just the roadbike being clipless and having the offroad mtb and commuter mtb being platform, but have converted all to clipless -- this winter commuting with clipless as well as taking the offroader on some pretty grungy and trying places - and feeling comfortable (ok, maybe a mishap or too) - I'm all clipless. Have to feel totally comfortable though - especially when riding in heavy traffic with lots of lights, right only lanes (and you have to go straight), etc. Have to add though, I love my mtb shoes - Diadora (versus my roadbike) - they are soooooo comfortable - they make a tremendous difference in the ride for me - and the want to continue with the pedals I have.
