I recently went to a 90mm stem from 110 and narrower bars after my usual double up foam/cork bar tape kludge didn't help much, I rarely ride in the drops and the double up normally solves a bunch of the hand/wrist/elbow/shoulder aches and pains.

I had managed to put the widest bars with the longest stem I had on when I built the bike up, it was all too much and solved about 90% of the problem by downsizing.

This is the before pic but you get the idea.
