RE: Summit Stands
Buck, it usually only occurs when climbing trees that require you to hook up the cable on the second to last barrel. This leaves a single barrel inside the tube and when you pull up on the climber portion the cable inevitably rubs against the back of the tree. This is most dramatic when wearing rubber boots or heavy clothing - anything that makes your ankles and/or feet less able to cleanly disengage the climber.
It's really the only negative I can say about the stand. It would be great if a solution were found. Like I said, I plan to dump a quantity of liquid rubber coating material down the inside of the tubes, but I have a feeling this will only have marginal results.
