So you’re gonna use a 5.9mm hitch on a 6mm rope and you think that would be sufficient or safe? This is my issue with certain new “elevated hunting” companies. Trc is only slightly higher than 3000 lbs. you lose strength for the sewn eye or knot to make the eye. You now are at 80% or so of that 3200 lbs so you’re at 2400 with rope that is technora and doesn’t stretch at all. A season into it you have a dynamic event, it breaks dropping you to the ground… then what? Is it really worth the “savings” for a substantial loss in strength and safety? The first one says it’s using a 2800 lbs rope and it’s not suitable for a tether. Linesman’s ropes ideally should be stiff enough to easily flip up the tree instead of reaching around and sliding it up.
here is my suggestion, before you trust your life to one of these ropes, e-mail the company asking for video of the rope being used for a drop test and ask for a copy of the testing report. If you truly do 3rd party testing, they allow you to video it, or they take pictures and include a report for the items tested and test methods which include hitch slippage, forces generated and also pass fail criteria. If they don’t do testing, they probably aren’t liability insured either so if you get hurt, your family has no recourse. Always put your safety first.
