I've been using Yakima products for a long time, and I've got
Yakima FrontLoader roof Bike Rack
on my OB right now and it has been my favorite rack so far. I hate taking the wheels off the bike and this rack has been really easy to attach to the factory rails and holds the bike really well.
On a quick secondary note, I've had two bikes attached to the factory rails and have been on some rough roads in Moab (I know, not recommended, but unavoidable for the most part, just take it slow as possible!), but the bikes themselves wobbled back and forth quite a bit, but the factory bars held firm and I've never had an issue with them, then again I don't haul canoes or kayaks like some people here do.
