mediavets yes I use that head, it operates very smoothly and requires handling just one knob that, when loosened, allows me to adjust yaw and pitch. You can unscrew the head easily.
Are you using a pano head on top of that?
If so which?
And if so, do you use a QR plate between the two?
I am currently using a large, quite rigid, tripod with simple 2-part large diameter tube legs with easy twist locks, that I got very cheaply on clearace from Kodak on-line some years back - some US brand I forget which - anyway it has a smooth 3-way head with QR plate on top of which I mount my Nodal Ninja 5L.
However there is some 'slop' in the setup - I think mostly in the QR plate area?
I like the idea of being able to mount/demount and level the pano head quickly - and the 3-way head and QR plate is good for that but I also want the setup to be more rigid when locked. And the control 'rods' for the 3-way head intrude into the nadir shot more than I would like - don't you too find that with your Velbon 200r?.
So I'm thinking it may be best to get another tripod (perhaps the Manfrotto 055X Pro which sems very popular with panographers) and do away with a tripod head and a QR plate between tripod and pano head.
I'm told that with a little practice it's quick and easy to level via tripod legs alone - if I find this too much of a hassle I'm thinking of a levelling plate or levelling centre column.
