I am about to set mine up this way. I was supposed to get a delivery of cord in the mail today but they screwed up. I may just hit the local shop tomorrow and get some. Mine functions 100% with the spring currently but I have never been happy with it. IMHO its purpose as a bounce dampener is only useful in cable driven configuration. As a limb driven rest there shouldn't be any bounce and if you do get any the arrow should be long gone. In order to get the rest working 100% you have to really pull the hell out of the cord stretching the spring. It just seems counter intuitive. FYI The cord retainer bolt they use in the old versa rest fits perfectly in the new threaded arm for the Hybrid FYI. Those parts should all be available from Hamskea.
