Anyone using/planning to use kayak carrier attachments with the Whispbar? I had asked them and they said Kayak carriers WB-400 and WB-401 will be available starting early May (not sure what the difference is between 400 and 401). Both seem to be only able to carry ONE kayak which is a bit of a bummer. I would've thought with the width of the Model S carrying two should not be an issue?
