I have the CCS, I like its simplicity and lightness very much. No issues adapting to it even on the first run. Without the chicken loop it allows you to bring the fully-sheeted-in position closer to your body, as well as the fully-sheeted out position so no back-bending to depower.
I dont ride TT, jump much or do circus tricks, just strapless surf, so that is my context.
Here is Ian Alldredge with a similar line system adapted to the BWS bar - but his only has the full-release snap shackle. The CCS is better in that it has the quick release to flagging option as well as full release. Its activated by pushing a release ball forward, similar to 'normal' chicken loop systems.
Regarding beginners, since they start with no preconceived ideas or habbits, I dont see any problem. Perhaps learning on a Cloud and CCS and then moving to the common system might seem strange, with all the added bulk.
I have not taken the CCS out in high wind and wave situations yet (ie smaller than 9m), and dont anticipate differences, but for bigger kites and lighter wind I think its refreshingly light and simple.
