Good Morning, Jeffrey,
I once pulled 140 ft of 2" PVC well casing that was too brittle for the standard puller using Prussik knots. The drillers were afraid that they were going to have to drill it out in order to close-in the well.
Since the PVC pipe is pretty smooth, I took 4 turns on the Prussik using a 'flat strap', since that was all we had available. The drillers and the other Geo swore that it could never work. It worked just fine - and we just shook it out to get a second grip with the Prussik, before we had too much pipe out of the hole and had to cut it off before the third pull. 140 feet of pipe comes out real easy when things go well.
The drillers were amazed that the Prussik knot worked so well. If you are worried, take an extra turn or two - as you know, just never allow anything to push on the 'top' of the Prussik ..... and stay ready to do a 'grab & slide' if need be. Strap up to the mast so you don't do an 'end over' and use a belay line over the spreaders.
Since you have a 'telegraph' 1/8" line, can you pull progressively larger lines using the 'telegraph'?
That might avoid going up all together.
Just a few thoughts.
Stay Safe,
Len
