Both. 2670 lbs main line especially an aramid main line is troubling enough because it’ll have a very low safety factor built in and the 7/64 amsteel won’t handle any accidental shock load very well. If the hitch slides that easily while loaded, it’s also very likely it won’t have the same holding power as more well known tried and true hitches. Amsteel doesn’t have a high melting point so if the hitch were to slide too quickly from a fall, that’s a recipe for failure. I hear people use the argument, amsteel is used for bridges on saddles. Yes but it’s 1/4” with over 7000 lbs break strength with a long long bury. It’s rarely adjusted so less subject to friction in the first place and most importantly it’s designed to be used in combination with other materials that help absorb the shock. With that “lineman’s” rope there is no shock assistance if you fell.. and lineman’s ropes are adjusted quite often while climbing so it’s possible that thin thin amsteel hitch is melted and you don’t know it. That’s a no for me until I see some rigorous testing done. If it can’t pass some ideal condition while brand new from the factory testing, how can you trust it a season or two in when conditions aren’t ideal? Again these are my opinions. I won’t say you shouldn’t buy it, I’m simply saying I wouldn’t and won’t until I’ve seen proof it’s safe.
The love affair with amsteel on this board is absolutely mind numbing to me.
