I didn't buy a ballhead yet either, that's why I am wondering which you show on that Benro tripod to get an idea of size.
Also with what you said about plates and QR...if I get a QR do I have to get a plate from the same vendor or is there something I should look for in the specs to make sure they are compatible? I could be wrong but I believe you just have to adjust QR's for the specific plate so if you used a number of them it would get annoying.
The ballheads in post #4 above are Markins Q3Ts.
Some vendors make lever clamps that are adjustable, others are more rigid in the kinds of plates they'll work well with. Some have better safety features than others. Acratech, Kirk, Markins, RRS and others all make quality clamps that are reliable. It's best to do your own due diligence to discover what you prefer.
did you pick the pro-gold from kerry?
Seriously.
