You guys would hate the bars on my bikes. They are all cut down to about 22". Anything wider feels awkward. I don't recall ever crashing because I didn't have enough control with narrow bars, but I have caught a few trees with wide bars. I agree that it is basically personal preference though.

A lot of the control issues have to do with the terrain you ride,and the type of riding you do on it.
The main thing is that we all agree and we all get along so don't be calling folks out on things you might see as sillyness and nonsense.
