Personally I like them to a point. I've compromised on 750's for my XC, trail and fatbike. That being said, I have gotten wedged between trees during XC races with the 750 bars. I run 780 on my rigid SS. I have some 800s laying around, but no bike for them right now. I felt cramped up when running 700 or less bars, but I have a bit wider than normal shoulders.
