Hemmed and hawed at this decision.
It was down to the NV rack, T2 Pro and the Saris Superklamp.
Their superclamp was nice, but I figuered 2" overall would be better - less rattle, etc.
So that ruled them out.

Then Thule has issues mounting 2 fat bikes which sorta pushed me over the NV rack. I thought long and hard and figuered I've got at least a 6-7 year jump on the possibility of 2 fat bikes needing to sit on trays, so.......I ordered the T2 Pro.
