On the package it says working load is 200 lbs or so.
But the specs on line gives 2880 lbs as tensile strength.

see here:

I'm a big guy and with a 30° hang with my weight 200 lbs of tension is possible.

Am I in danger of catastrophic headfirst midnight dismount (CMHD)?

If my math isnīt totally wrong the tension on your line (with a 30° hang and weighing 200 lbs) would be 400 lbs.
If the poly rope can take a load of 1980 lbs that would give you a safety of approx 1:5.
Thatīs (for me) enough.

But, and theres always one, is that the rope might be difficult to handle, it might not be weather-resistant and so on.
But, test it, and let us know how it works.

Says me, who is thinking in the same direction.....
(Because I canīt get any Amsteel Blue where I live)
