"I use a Hollywood Microdolly for much of my work, ti's easy, smooth, lightweight. It won't handle a heavy cam, even though the manufacturer says it will, but for 15lbs and under, it's a jewel."

I don't understand this. I'm using one with a 22 lb. camera, and can't for the life of me figure out what the problem would be even with a camera that weighed twice that. Per their recommendation, I'm not using the factory tripod, but Cartoni carbon fiber sticks and a refurbished O'Connor 50 head.

Of course a rigid tripod and head is required, but with that I am scratching my head over what could go wrong???
