Ive been told to milk new climbing ropes. Is there a danger to not milking or is it only just that the sheath with bunch up? I have a new role with one side that has a sewn termination. I milked it once and cut with after wrapping with electrical tape. Should I only climb from one side because realistically if I climb from the other end and switch back and forth wouldn't I be milking it toward the sewn termination?
