I also installed the Aeroblade and it works great. No real noise with just the bars - a very faint whistle at high speed. A bit of noise with two bike carriers mounted, but you really can't hear it over the stereo. I got mine from Rack Outfitters in Austin - they offer them powder-coated in black. I think the all black rack looks awesome - really glad I found these guys.
