I agree.  I used to sell roof racks, long ago, and I've seen lots of bent
cross bars, but never on a Yakima.  Also, because of the round bars, bike racks
and other things always line up correctly.  With square bars, if you have any
curve in your roof, or your bars are not in the same plane, you will have to
bend or loosen everything to make things fit.  With the round bars, you just
rotate the bars to align everything.  (this actually does make sense...planes vs.
tangents)

I also saw photos of a roll-over accident in which the Yakima rack was the
only thing that survived intact.  The Yakima rack system is stronger than your
raingutters.
