I'm thinking about getting one of those giant 7-foot diameter parabolic umbrellas -- Wescott actually makes one that is affordable, although not as deep as the ProFoto $$$$ one -- but rather than using the puny umbrella mount on my light, I'd like to find a reasonably portable yet sturdy umbrella mount and robust stand to mount the umbrella on. And then I can move my light(s) independently and not worry about stressing out their mounts.

The umbrella mounts I'm seeing are mostly for flimsy light Strobist shoe-mount flash stuff. Yet I don't want to go with heavy-bulky Matthews C-stands. What's a good in between?
