Andrew K.wrote a review of Yakima HullRaiser Aero w/Tie Downs on July 21, 2012
Bought two sets of these and they are great. They're pretty easy to install and take down. And they fit my wide factory bars (Nissan Xterra), which not all racks do. They hold my 12' recreational kayaks securely. I've taken them on a several hour trip on the interstate and none of the straps came loose at all. I do have one tie-down strap that is starting to fray--not sure why. The one thing that I do not like is how difficult it is to adjust the pads on the J-cradles. It is necessary to adjust these to make sure that your kayak is resting on the padding, but they are extremely hard to move. Overall I would recommend these as a good choice, especially if you have a Nissa Xterra.
