Wayyyyyyy back in the day I had a very narrow bar on my '93 Stumpjumper. It was great for fast trails and fitting between tight fitting tree's. Sometime along the way bar ends were replaced by wide bars and short stems. I replaced the bar on my current MTB and I bought the widest bar I could find. I used this over a few weeks cutting a bit off the end of it until one day it was way to narrow. ooops!! I measured it and bought a bar that was close to the size before my last cut.
Anyway, the point being is everyone has a width they prefer. Try a wider bar and see what you think of it and find out if it is Nirvana for you.
