I've had my 1.7 DL for well over two years now and have NEVER had this problem. I'm an experienced hanger and have tried all the known remedies (at least the ones I have read here) for calf ridge pressure. I recently hung my hammock from two eye bolts in my room and am sleeping full time in it. First few nights, no problems. Literally haven't changed anything and for the past few nights I've had major calf ridge. WTH? Why Warbonnet?
