ROFL!!
Any chance you'd care to elaborate on Atlas' performance, relative to traditional sub-2% bull rope, for negative rigging? Was just discussing it in another thread, I'm using 3.5% polydyne 5/8" but plan to get 5/8 Atlas when my polydyne's compromised, on-paper math has Atlas out-performing Polydyne (and every other 5/8 or 3/4 available) by an insane margin for dynamic strength (ie staticABS // elasticity-@-10%ABS) A given log, say 100lbs, being free-fallen to a snub-catch, done w/ 5/8 polydyne from one drop and 5/8 atlas from the second, should see at least a couple feet of extra free-fall capacity from Atlas (depending on length of rope-in-system of course, could be even more dramatic in fact I'm confident Atlas will bring the entire bull-rope market's average-elasticity upwards as it(atlas) shows more&more how important dynamic-capacity is to rigging!)
5/8" Atlas with a quick shackle is what I use for negative rigging anymore. I used to use polydyne for everything, but I've switched to double esterlon for rigging out canopy and swinging wood, and atlas for blocking down. Polydyne is still one of my favorite ropes, and if you have to choose one to get it done, would be my choice. The elongative difference between 5/8 atlas and 5/8 polydyne is very noticeable, especially in a scenario where you are pre-loading the line. Polydyne seems to be able to store energy in its elongation when loaded for pulling, whereas atlas is very rubber band-like and you just fight the stretch. I notice a difference in negative rigging, but not as much, which may be due to the fact that my crew can run the rope buttery smooth. I can't comment on any anecdotal strength difference, I rarely block pieces over 1000#, and like my system to be way over-built. I love pulling out the atlas. It's a super pretty rope, great hand.
