I'm glad to know my comment could be of help, and in the spirit of furthering that:
I looked at many of the options listed in the original post and even tried a couple that were on bikes around town. What made me settle on the sparrow?
I needed something compatible with MTB style trigger shifters, fairly narrow, and something I could flip for a more aero position.
At first, I thought the Mary bars were awesome--and they are, in fact they're perfect for off road riding, little bit of a rise, great sweep so your wrists don't hurt and they're nice and wide for more technical turns. They were just TOO wide for me to ride on the street.
The sparrow just loooked like it had the perfect bends for wrist comfort, enough of a drop to it that I could tuck down and, I'll admit it . . . they matched the color of the bike. There I said it. The bikes' black, the bars are available in black.
Like I said, I just put them on (two days ago). Maybe I'll drop back by after I've got a week or so riding on them.
