See if any of the shops carry North Roads style, Moustache style, FSA Metropolis bar, Mary On One bar.
Ask for anything with at least a 40 degree back sweep. the reason you want to try to find it in a shop is that bars are like saddles - you need to try them out - and the back and forth online shipping can mount up. Also, many bars can be cut down if they are too wide (doesn't work with a high degree of back sweep). If your current bars are fairly straight but too wide, you could try cutting them down (your local shop can definitely do that). Maybe it's time to go visit a friend who lives where there's more shops? A trip to Santa Rosa? NorCal Bikes is a great shop; I had my bike fit there.
