The Wild One Chubby 575's are much better bars than stock, but I was still reaching down and was killing my back on long road trips. I decided to try the Paul Yaffee Originals 12" Monkey Bagger Bars.
They are definitely more difficult to install. Much harder to pull the wires around the sharp corner. In addition, you need to get new clutch and brake lines. Both of these lines required bleeding which is also a PITA and messy
I was concerned, from threads that I've read, that the Zumo 665 would be blocked by the bars. I purchased a swivel for the Zumo from Crutchfield that angled the Zumo where I pretty much have full visibility.
I just finished the install, so I haven't had a chance to try them out. Sitting on the bike, my arms are now level which should help my back. I also thought they looked pretty good.
Here are a few pics.
