So i started using Whoopie slings a while back for the convenience (and my love of fiddling with rope.)
My only problem with them was that i was now carrying double the amsteel that i used to when just tying a "hennessey 8."
So after a while of missing only taking half the amsteel..... i ditched the Whoopies
I know, I know, you guys are all thinking "but amsteel takes up no room and weighs next to NOTHING!"
Aaaanyways i was back to tying knots again, and the next hang in a big storm started REALLY missing the quick and easy adjustability of Whoopies.
Got me thinking "why not just use the constrictor part of the whoopie and save doubling back on the adjustable loop?" of course you need both ends of the constrictor knot under load to "lock" the knot so i tied a small bowline attached to a prussik, attached to the main line. (after testing I found that you do have to crank hard on the prussik to lock off securely or it will slip)
If my math is correct, this system should save me carrying about 8ft of amsteel per 10ft whoopie sling!
Thats about 16ft less amsteel in total!
Those extra tabs in the pic are bowline ends I had to tie instead of burying the ends, as i needed as much hollow core as possible for the main bury to keep length down.
It does look a little more untidy than a Whoopie
So far have only spent an hour in the new system and it seemed to hold.
A long overdue overnighter will put it to the test
Any Feedback on improving or possible drawbacks of this system would be muchly appreciated.
