Although I know no competition ball heads, but which can not be better. Of course, the Novoflexprodukte cost a little more - but that they are also value! I use the Classic Ball 3 II with Q = Base quick coupling and Q = plate PL 1 clamp. That nothing wobbles and will not budge. Even with a 70-200mm / 2.8 remains the holding position. I was and am willing to pay the higher price for the Novoflexprodukte.
