One of the chaps from Treesolutions has just taken delivery of the new two ring cambium saver or multisaver from teufelberger. It looks like a tidy bit of kit and usefully requires the same size retrieval ball as a rope guide. He has replaced the adjustable section with a cocoon attached by a softline prusik loop. This is installed around the TIP with the big ring on one side and the cocoon and small ring, in that order, on the other. Nothing unusual yet I know. However, the climbing line is passed through all three points and the prusik loop adjusted so the cocoon sits snugly in the middle. This seems to drastically reduce the friction associated with a normal two ring cambium saver, infact it performs more like a rope guide but without any of the retrieval problems.
Just wondering if anyone else has used a similar setup and how it performed?
