I wouldn't want to use a ball-head with a 600/4.
A pan-tilt head would be totally out of place on a monopod.
A gimbal head might work OK, but I'm leaning towards agreeing with
Cotty's suggestion of not using any head. Once that 600mm is moved
off-centre, the whole monopod system would be in danger of folding at the
pivot point and falling over, especially if the monopod is leaning. And
if it gets the chance it'll eat your fingers in the process.
Depending on how the lens balances, some sort of head might be required.
From the pictures, it looks like the socket is well positioned.
My 600's balance point is about 6 inches from the tripod socket (with the
istD mounted). If I want it to balance, it has to have the support well away
from the mount. I expect on a monopod, I would have to use a Kirk QR
directly attached to the monopod.
