I've been trying to find a good tripod head for my Calumet C-1 now for some time. I've got one of the magnesium Green Monster beasts. I have a Bogen 3039 head with the quick-release, and while that holds it ok most of the time, the camera has a rather unpleasant ability to torque around on the quick release plate when you need it to move least (like when you've already set your composition and focus, and you are inserting your film holder). I tried an older large platform Gitzo head (an R #2), and that was more wogglety (nice technical term there) than the 3039. Same with a Gitzo 1377 ball head. Is there something out there (aside from a $600 Arca-Swiss ballhead) that will do well with this camera?
