I use Thule for function, they look OK, all black to match the rails.
Five minutes on and off, with locking caps.
Easy to switch between my two vehicles.
I stopped using the ski rack attachments and just put the skis inside.
Check my profile picture, you can just see the rack!
I can get one kayak and a canoe, or 4 kayaks at a time.
Also tried Thule attachments for tandem and two single bikes.
