Any special things I should look for in a roof rack that might differ from a DF?

Vehicle: '97 RAV4 with OEM roof bars.
Bike: TW-Bents, elegance.

It looks like a standard fork attach rack should work, and the wheelbase is short enough that I don't think it will be an issue. Anything else I might have to consider?

I'm thinking either the Thule Domestique or Yakima Forklift at the moment.

Thanks.
