This is my most recent sling! It's undergone a lot of experimentation, but I'm fairly happy with the finished result. It's got an adjustable finger loop (The inspiration for which came from from one of Jaegoor's slings; I'm not sure it follows the exact design.) The adjustable loop is basically a regular finger loop ŕ la the Dan Bollinger pictorial (
http://www.slinging.org/articleimages/20/19.htm ), the difference being that it's super small, and the rest of the sling is fed through it. It works, at any rate.
In all of my previous slings, I simply had a knot at the end of my release cord, but these would eventually "slide" down the cord as they tightened, throw after throw, and threw off my grip. For this one, I made a second loop where I felt the cord should end (I thought of it like a sword's pommel), which has stayed in place since! I originally had braided the excess cord into a kind of trailing "tail," which, I eventually noticed, produced
way too much drag. I sawed it off at the end of the loop, and
voila! I was left with a cool "split tail" that produces less drag, and still helps the sling to stay the same in my hand throw after throw, just like the original "pommel loop." (It also makes a satisfying, dull popping sound on release.)
The braiding is a bit messy toward the release end, since I had to braid in additional strands to make up for the shorter pieces I used in the beginning, but it still holds up fine.
