Mike,
Good idea about leaving a generic plate in the AS clamp on the tripod. But ALL the AS plates that I have and have seen, require a hex key/allen wrench to secure the plate to the camera. So not that easy to do. I would love to find a plate with a thumb screw. Time to go eBay shopping.
Mike and Bob,
I did not know a Bogen hex QR adapter was made.
I found it.

One good thing about the Bogen/Manfrotto hex plate system, is that it auto locks when you put the plate in. So no fumbling to secure the camera down.
