I currently have a Manfrotto 488RC4 Midi ball head rated at 17.6 lbs., sitting on a Manfrotto 055XPROB tripod rated at 15.4 lbs. I also have a Berlebach Uni tripod thats rated at over 100lbs used for astronomical observing with a 90mm refractor. So, I think I'm ok in the support department. Sounds like I may want to consider a pan/tilt head for LF use at some point.
