I love the versatility of the Contour, especially the zero degree angle for getting into difficult areas. I fits both my ettore and sorbo super channels. I have Contours on most of my channels. Though you should carry extra mechanism parts so that I don't have to replace the whole handle when I'm only missing a nut or the little wire crossbar. It could be similar to the parts kit that you offer with other quick-releases.
