Anyone have any recommendations for a rack? The Malone and Thule sites fit guides do not have a solution they recommend. Amazon reviews slam the Malone's ability to clamp on the rails effectively. Anybody use a Thule model they like or any other recomendations. I just spent alot of time and effort on this CH18 and I don't want to take any chances while transporting it. It will be on the highway at speed for hours to get to a paddle destination.
