Smallest diameter on tether rope

Anyone using 8mm accessory cord for a tether or bridge? Thinking that for tether and bridge with a 1/4" amsteel loop for prussic would be a nice compact setup. Seems to be rated fairly high, 4200lb tensile strength.

I'll be using Samson ultra-tech 8mm for my linesman and tether. 7800lb rating

I’m using 8mm tether but am not sure what it is. It’s paired with a Kong Duck.
I think I’m going to try the amsteel prussik and see if I like it. But I definitely like the 8mm better than the bigger ones I’ve used in the past.

1/4" amsteel in a continuous loop worked extremely well for me for several hours yesterday on the Predator rope that came with the Kestrel. No slippage on my bridge or tether. I put it through several "tests" and it worked great.

A hollow block is small light and designed to be used as a prussic and can be used on a very wide variety of rope widths. It slides easy and locks well. For the cost I would agree with Red it is the better option. I have used the hollow block and they work well. That said I have never used amsteel that way.
 
Redsquirrel certainly has more knowledge and experience than I. I do know it worked well for me yesterday, but if I go to 8mm rope it may not have such a mechanical advantage. 1/4" prussic on 11mm vs 1/4 on 8mm may be pushing it.

I was thinking 7/16 is what I need. I like to tinker with different setups and I’ll try it and see if I like it.

I would be extremely cautious using amsteel for a prussik. Even though a continuous loop with a prussik is technically not a "knot", they're several knot like bends being made. It will work great, until it doesn't.

Sorry I'm just catching up on all the threads now lol.
You just don't gain anything by using amsteel here. The hollowblock is probably the same size if not smaller and very light. It will definitely work on 8mm rope. You just may need to give it another twist to get it to bite.

Another thing I would do is flip that bridge to tether biner so the gate is pointed out and the opening to the bottom
 
I am using Teufelberger Reep Schnur 10mm for everything on my customized Web . I use it for my primary bridge,my secondary bridge for climbing, my linesman/lanyard setup and my tree tether with the Rockman. Lightweight, knots well and is a cool green to boot.
 
I have used 8 mm ultra tech with a kong or CT roll and lock or a ropeman 2.

I have also used the above for a linemans belt. It is significantly lighter and still very strong.
 
I'd use a 28" 8mm ocean eye to eye over amsteel for a hitch.
