One of my high quality ball heads does not offer an OEM 3/8" tripod screw option. The only way to go is to get a 1/4" to 3/8" adapter. I have a few older ones but not that high of quality and the brass one scares me a bit to use. I would assume that a SS 1/4" to 3/8" adapter would be the best way to go or ? Can anyone recommend a high quality 1/4" to 3/8" adapter?

Only a personal observation, but 1/4" tripod screws seem to now dominate the current market. Probably just the result of digital cameras vastly outnumbering LF cameras...
