I resisted them for years, but finally tried some Jones bars (butted H-loop, 660mm) and I
really like them. I use the loop, but wouldn't mind trying the non-loop version as well. The Jones bag fits inside the loop perfectly though, and I use it a lot.
I initially thought that I wouldn't like all that sweep (45º), but it turns out that I like it better than any other alt bar I've tried, including the Ritchey Kyote ( 27.5º), On-One Mary (21º), and Surly Terminal (34º).
As for width, the 660mm feels pretty right. I had to cut down the Kyote (800mm) and Terminal (735mm).
If you haven't checked out this bar comparison tool, it's pretty useful:
