All of my bikes now have swept bars. I've been happy with:

1. Origin8 Citi Classic
2. Velo Orange Tourist
3. Steel bars from old Schwinn

My situation is that I can't ride drop bars any more, and MTB bars wreck my wrists. The swept bars are a lot more comfortable, probably due to the wrist angle, along with moving the grips back by a few inches. I even find that I really don't have to change hand positions, though I seldom ride more than a few miles at a stretch before stopping due to traffic.
