All I can suggest is that the RaceFace bars I've been on for a while now have zero vibe/resonance issues that I can detect...and also do not give any unwanted flex that I can detect either. Great bar for moi.
The 785's...Atlas I think.
I use thicker grips and usually gloves too.
fwiw....I just started riding Trail again (picked up a new Trance)...put the 785's on it from my DH bike, and I gotta say...it's feels like too much leverage on such a light bike. Will be experimenting with moving my grips in.
