A Moving Rope System (MRS) has a rope folded (doubled) over a tree crotch and one end of the rope attached to the climber directly and the other side is attached via a friction hitch or device.
Background: Some folks still call this DRT, but MRS is the correct term. The acronym DRT = DOUBLED Rope Technique, where “doubled” means “folded over”. In contrast, DOUBLE Rope Technique (also DRT) comes from mountaineering and involves 2 separate ropes. Some call it DdRT to try to distinguish the two. But inevitably, not only was the acronym not clear, but most of the folks using the technique incorrectly call it Double Rope Technique instead of Doubled Rope Technique.
Below, JRB demonstrates a self tending MRS system using the Longhorn Agile Hitch. Overall, JRB does not recommend MRS for able-bodied saddle hunters unless they have a physical limitation which prevents them from using DSRT or SRT, which are faster and more efficient.
