I have an Inno rack from ORS Racks for my Fit. I just posted a review of the rack on paddling.net. I have no problems with the Fit as a kayak hauler, including hauling two big, heavy 16 foot poly boats that I keep in Maine. No experience yet with really rough roads, but with the bar spacing only around 30 inches, those heavy 16 foot boats tend to pitch up and down (i.e., "hobby horse") when I hit big bumps. So bow and stern tie downs are pretty critical to help hold the kayaks securely. But I don't have kayak cradles, just the boats sitting on the bars with some foam in between, which contributes to the boats moving around on the rack.
Here's a smaller 13.5 footer on my Fit.
