On our '06 I had the Thule feet that went in the track and then the cross bars just went on or off with the turn of the key. Right now, for my '12, I have the Thule bars that strap on around the raised rails, but they take forever (vs the old style I had) and I'm always trying to get them straight and even. Is there anything that's simple to pop in and off the roof? Are the factory bars simple? Any insight would help.
