Jamie,
Please have a good look and play with Sinar arTec.
I own a WRS for 2yrs now - happy with it! but I also had the chance to recently play with the arTec again. Only wish someone could have taken my WRS off me 6 months ago or Sinar given me a good deal 2 yrs ago!
I have a HR90mm (very large IC) and currently, Cambo cannot TS mount it yet. As Cambo tarts to grow with this WRS system, many more lenses will be able to be TS mounted.
The arTec TS is on the camera body. Tilt and rotate the plate and you have swing (just cannot do both at once). So effectively, any HR lenses can be used without needing special moutning.
Good luck...
