Roof Rack Wind Noise Reduction

I was offered a great deal on Thule 65 inch bars and mounts for my Chevy Tahoe before Christmas at Aquan and jumped on it.  Good news is I now can load 2 yaks upside down and offer carpooling, some bad news is its kinda noisy. 

I looked at fairings but it seems the attachments are going to be on way when loading yaks upside down.  I saw the Yakima Windjammer http://www.yakima.com/shop/racksystems/naked-roof/windjammer

One dealer told me it works with Thule bars.  Does anybody have any experience using them?

my wife's actually got one on her subaru- suprisingly works

I had a Trooper with Yakima racks and the wind noise drove my wife nuts. She did some research and bought me a fairing for xmas. It was considerably quieter.
