Anyone have any hands on experience with the Millennium mounts? More specifically, the telescoping double mount. Not much info out there, as far as reviews, that I can find.

I really like the amount of adjustment it has, but am curious as to how it is in comparison to a Stowaway or Cornfield folding. My biggest concerns are how it will do laying flat, in rough water, with no kickstand, and if folding it up and down will be aggravating due to having to loosen and tighten the knob each time, due to not having a quick lock like the Stowaway or Cornfield.
