The online store that carries the Wieldy Vest Stabilizer system recently posted up a new crane / jib that uses a cable driven tilt head.

This allows the operator to adjust the angle of the camera by tilting the angle of a Video Fluid Head (much like the Varavon Tilt Found Here). The total telescoped length is 10.5' (feet) but can be adjusted to operate shorter. Check it out from the eBay seller following the link (here).
