Good morning gang,
I'm in the market for a ball head for my tripod. I'm going to be doing macro work and my present tripod head is too much of a hassle to adjust. I figured a ball head would allow me to very quickly position the camera precisely where I want it and then be able to lock it in place with a switch. Obviously, I'm using 35mm (Nikon F3) and the lens is a 55mm f2.8 Micro, so there's not a lot of weight.

What experience do you people have with various ball heads? Are there any I should avoid? All input would be helpful.
Thanks in advance,
