I finally bit the bullet and purchased my Thule Roof rack from the RackAttack Vancouver store.
The components are:
480R Rapid Traverse Foot Pack
1312 Traverse Fit Kit
ARB47B 47” AeroBlade Black
544 4-pack Lock Cores
Not inexpensive by any means, at a cost of over $700. taxes in. But I’m very happy with the quality and fit/finish. I do not notice any increased wind noise and the AeroBlades do not require a wind screen.
