Since we are talking about ascenders, has anyone tried the Petzl Stop? With my little experience, I would say avoid this one as its too tedious, but maybe theres an easy way to use it Im missing. Once its figured out I imagine its easy, but compared to the mini-traxion I use up top its slowwww....so far. Mini-traxion compared to Tibloc is not fair at all. Point of tibloc is light-weight and inexpensive. I understand if you dont have the money just use a prussik then, but what about ascending in the water? So maybe throw in a Petzl shunt?
