Thanks everyone for the help. Trying to plan this trip is a challenge!
Well worth it though!
I think I may go with a Thule product. I have the SPT straps that look just like the Kanulock. Same company for sure... Anyhow, i found it annoying to get the lock to work. To engage to lock, the handle needs to clamp down on the strap with sewn in cables which was not always easy to do. If you did not squeeze the straps hard enough (lot of effort!!!) you would not be able to turn the key!!!
So this is why I do not have faith in the Kanulock. Did someone mention that they have a new key and system? I do not think the key was the problem though... the overall concept of having to pull really hard on the leaver to be able to lock is flawed!
The thing is, my roof is packed already. I have a box, 2 bikes, camping gear, two kids, 4 kites, 3 boards..oh, and a wife.
This all has to fit in by subaru wagon. My plan is to pack the Box with the kites and camping gear in it. Move the two bikes over as much as possible towards the box and then tie down a board bag with my 3 boards.
I'll take pictures of the setup once i leave in a month and review the Thule straps in the same time.
