The Thule rack that I purchased is a must for any kayaker with a truck. With the combination of the Thule Hydro Glide and set saddles, loading and unloading a 60 lb kayak is no problem. There really is no humming while going down the highway as long as the weather-strips are applied. Otherwise, great rack for the money. Plus, it won't rust like Yakima's rack. Been there, done that.
