how about if main use is for tracking moving subjects?... is the movement smooth?... sorry for OT...I would not recommend a Jobu. Especially if you have used a wimberely sidekick or the gimbal before.
I bought a jobu once and sold it immediately (ie 2 days later) @ 40% off , it is not worth the buy at all. Unlike the wimberely you need to really use force to tighten the swinging axis and yet it moves.
