The Manfrotto Hydrostat ballhead tightening knob is rubberised, thus half turn with very little effort it is tight already and very easy on the fingers when tightening the ballhead. Good find I must say and thanks to Merciless Knight PM replies on where to buy, I just bought it.
In case anyone interested, my check with CP suggested that they are bringing this Hydrostat ballhead in end August, Merciless Knight told me where to get it (not CP) and I think I bought the last piece. :sweat:
I think the main selling point is that it 'employs a revolutionary friction and locking mechanism. An inner oil chamber is compressed by turning the locking knob, exerting even pressure on the whole of the underside of the ball, which ensures sturdier locking and higher capacity... for camera and lens loads of up to 10kg.'
