Grant, I currently use Wimberley II, and I like it a lot. Used 400 f/2.8 IS MkI on it, and now it's 800L mostly.
However, I must say Jobu Pro 2 is at least as good.
Those two gimbal heads are similarly heavy, similarly priced, and both solid and built to last practically for ever.
I am scared of ballheads, and sidewise lens mounts I find distracting. There is something to be said about heads that work with gravity, such as good gimbals do, as opposed to fighting it.
