I'd be very interested in hearing back about the results to that test, if it was ever done.
We're in a similar situation on 2 major keywords. Our competitor has stronger backlinks and every few weeks swaps with us for no 1, but we don't know their traffic obviously.
Maybe an experiment with a small ads listing?
Any feedback on this one?
