Joe,

When you talked to Yakima did you ask about using one of the bags instead? (see link)

It appears that the mounting system is strap-based instead of hardware-based, so maybe this would be a universal solution? Not as cool looking as an aero box, but would be lighter, cheaper, and easier to store...

Thoughts anybody?
