I had made whoopie slings for my hammock and thought why not whoopie slings for my tarp ridge lines?
These could be useful with or without the hammock, tied to trees or staked with trekking poles.
Whoppies allow for ease of adjustment without knots, less wear on the line and whoopie slings are stronger than knots.
So I made a pair using 1.7 Zing-it.
After I was done, I thought maybe I would modify my other guy lines with fixed brummel loops on one end and a backsplice buried ends on the other.
This would allow a clean appearance, no fraying of the ends and less wear on the line.
My other guy lines are 250 lb Dacron kite string. Both Zing-it and Dacron kite string are hollow braided allowing for splicing tricks.
Here is a picture of one of the whoppie slings for the ridge line:

I prefer Zing-it for it's strength to weight ratio, but don't like the way it handles knots. I won't be tying knots on the ridge line because of the whoopie slings and a marlin spike hitch on the end.
I will be tying knots on the other guy lines, so the Dacron kite line was chosen.
I had investigated using whoppie slings on all the guylines, but the whoopie slings are limited in how short they can be and so wouldn't allow a close ground pitch when needed.
