Amsteel 1/4" prusik on 8mm sterling oplux?

It seems slack in a tether line is a serious enemy in regards to our hunting methods. It's impossible for me to climb or descend (I use the seat portion of the LW hand climber as my climbing method and platform) without introducing slack in my tether to move it up and own the tree. However, with my new found knowledge from this thread, I now know to make reducing/removing slack in my tether a priority in keeping myself safe.

If you're concerned, get a Yates Screamer (I'd get the Zipper one).

If you want your mind blown, look up on youtube the tests DMM has done dropping weights onto dyneema slings (I believe the core of Oplux is same or similar). It snaps way easier than we'd all like. A weaker nylon sling does better in the drop tests. I believe the Canyon rope is nylon core. This might mean it makes sense to use it over Oplux if you have any concerns.

I haven't watched the videos, but I'm not sure what he is trying to prove. These static ropes like Oplux give both a MBS in lbs and a max breaking force in kilo-newtons. The kN number tells you how much dropping force it can handle. Do his tests contradict the listed maximum kN dropping force for these ropes?

I'm more concerned than I was the day before yesterday, but I don't think any extra devices are needed for my peace of mind. My changes will be paying more attention to the slack I have in my system and I'm considering maybe a little heavier tether rope, like 9 or 9.5 mm, just to give me a little extra margin of safety.

I just do my best to always keep low slack. I climb using steps with both a tether and lineman's lanyard. After each step, I move my tether up and adjust the slack. The lineman's helps me do this and I figure that if I fall with a lineman's used correctly then it will slow me way down and the tether is there mostly to insure I don't keep going down the tree (fail safe).

Exactly. Such a short piece of dynamic that we would be on would generate damn near same amount as static

That's built into the calculator. You get to input how long a section of rope the force is acting on. For example if your in a very small tree. You could input 3', leave all parameters the same and just change the rope type from static to dynamic and see how it changes the kN. No need to guess, just input it and see. That's the great thing about a calculator for fall failure.
 
People use tenex and tenex tec ( a synthetic hollow braid similar to amsteel) as hitch cords, ring prussics, etc all the time. The main thing is no heat resistance. Although theres a new tenex with a red core, idk if that's any different. Easy to splice, strong, durable, grips well..plenty of reasons to use it

The Canyon has a polypropylene core, Oplux and RescTech have dyneema cores with an inner core of polypropylene. The Oplux has a bigger percentage of poly causing it to have a lower break strength.

The core in the Tenex is probably just it keep it round, Icetail has one also.
