FLM CB-58FTR Professional 58mm Ballhead with PRS Button, Supports 132lbs.

This is one of the best ballheads on the market. Seriously, it is fantastic. It isn't, however, particularly light.Note, I replaced the platform with a Really Right Stuff clamp and actually need a tripod head which is this beefy: I shoot large format film and the moment arm on the tripod head can be significant.
