I have a set of Thule Aeroblades on mine. I was very impressed at how little wind noise there was after the install. I checked inside cabin noise level with a little iPhone dB meter before and after at highway speeds and the net change was no more than 2dB. I have since added kayak J cradles which do in fact contribute to wind noise but I am still surprised at how little. Here's an earlier post with pics of my Thule rack. Thule AeroBlades - Pics
Thanks for the info CollegeBoy. All reviews for both brands' versions seem to be real good. Gotta find a tie-breaker and it might be that Yakima offers an HD variant which may be very handy with things like lumber.
