We have finally reached the point of no return for our roof rack and our bikes - we have Yakima vipers and bikes with hooded fork drop outs. It's a miserable combination and very difficult to secure, and this weekend it resulted in a bike fork hitting the roof. We could go back to upright bike carriers - but have found those frustrating in the past (due to bike types). We would also like to be able to carry the kayaks on the roof at the same time. So...we are looking at putting a hitch on the car (2011 Jetta Sportwagen).

I'm having trouble finding good data on what might work for our bikes (I know there have been other threads - but not with the odd assortment of bikes we have) - so I'm (of course!) asking here.

Requirements:
Easy to load (the current rack has become such a pain we dread loading it) - I am thinking we prefer a tray for stability and ease of loading (we had a top tube hitch rack years ago and hated it)
Must be able to deal with fendered touring bikes
Must be able to deal with disc brakes (on my bike wish list)
Ideally could deal with a Bike Friday (20" wheels, low mono tube) - they can go in the car because they fold, but sometimes there isn't room
Would like light - but this isn't a deal killer

Ideas?
