I installed the SW Motech bars on my '09 CA V and like them. It took a tad bit of fiddling to get the fit just right on the left side and at first the canister caused problems with extra vibrations.
I ended up installing strips of bicycle inner tube rubber anywhere the canister, fram and ubolt mount touched. I'm perfectly happy with them now and there's no more extra vibes.
I've also heard the the HB bars can be mounted after you modify the canister cover a bit to allow room for the bar. I've not done it but it doesn't look that hard to do with the proper tools.
