I did a search and it seems most people are running a J rack to haul their kayaks. I was hoping to get something so the kayak can lay flat. I have a set of Yakima Hullyrollers and Saddles that I want to put on, but am afraid with the spoiler in the rear that it might get damaged. Can the spoiler support the weight of a kayak as a pivot point? I have an Old Town Dirigo 12' kayak. Any other options that I could look into?
