For some time; i've been trying to crunch from time to time; one of Tom's puzzles, of a smoothly sliding friction hitch for SRT. It seemed that it would just have to take 2x the load of the double legged support of the more common DdRT. i think MM and others tried as i did, even to come up with some kind of hybrid crossover of metal and line to do the deed, dissipate friction heat, slide easier etc. It always seemed that the hitch tightened down so much more, especially as you went to move in SRT. Indeed it seemed that you had to totally unload it (by standing as support etc.), to affect the slide sometimes.
If the 2/1 of less loading on the DdRT was the only key; why could a 300# man slide on DdRT, and 100#man couldn't on SRT?? Even though friction hitch is running 2x faster than body in DdRT??
i've come back around to an old theory, with firmer resolve. In the DdRT, the load switched to the Static leg, as the Dynamic leg extended. The same as if that the lines were seperate and the Dynamic leg was more elastic, being lowered, tearing apart etc.; the Static leg quietly takes over the loading to compensate. Even the most basic lesson of the most basic Square/Reef Knot shows these mechanics (as i now kick myself fer the blindness).
i think the weight has to come off in DdRT as in SRT for the hitch to slide. DdRT, avails the Static buddy helper leg even in this loop of 2 legs, but not seperate lines; SRT offers no such strategy.
We now continue with the normal programming...

edit: i'm ~140# weakling, dressed, dripping wet, full meal,helmut, saw, rope etc. and had this 112# scale to test all this with....
