I remember when these first came out and I remember they were called "Gorilla Grip.' Now all I see is "Gorilla Pod" at Best Buy and they're smaller and only hold 300 grams. That won't hold a PM2 with 300 gram lens! I always wondered why they don't have 4 legs. Hmm. Anyway, what's a good one? It has to be small enough to be portable but the legs have to be long enough to wrap around the top of a fence rail and hold at least 600 grams. I'd say 8-10 inches is a good length for the legs. And it has to have a detachable head so I don't have to keep screwing and unscrewing into the camera all the time. Anything you guys can direct me to? Thanks!
