I currently use a 4x5 that weighs approx. 20 lbs.. I use a Bogen 3036 tripod but need a good head for this tripod. Something that will hold the weight and give preision movements, ie., tilt, pan etc.. Also I've seen ball heads and the kin d with the different handles (is there a name for these?). Which are more effic ient, more productive to use? Also what about mounting plates. Do these give th e camera more support or are they used as a quick release mechanism? Any input is greatly appreciated. Thank you,
