I find the Poison Ivy greeeaaatttt!!
It's very supple, stays round even in knots and through devices, is very abrasive resistant since its 24 strand braid, is more substantial to grasp than 7/16" and almost can't tell that it's not quite 1/2", can form and hold knots easily, is the lightest(6.5lbs/100ft) per lb. arborist rope made, and dries quickly after wet and the strength is 6500lbs.(a little more than some 1/2"ropes)
It is also spliceable and eventhough is a Kernmantle "type" construction it is a true braided two ropes in one arborist rope.
It is also very low stretch. Haven't had it glaze easily yet either.
It can almost brush your teeth!--just kidding.
Can you tell I love it?!
