I just discovered that I could use this sling either as an y-sling, or as a regular sling
If I want to use it as an Y-sling, I release
both release cords on a throw.
If I want to use it as a normal sling, I only release
one of the release cords, while retaining the other. This means the projectile will roll out of the pouch as with a normal sling and get the friction that is needed for rifling.
This means I potentially have a sling here that is both optimized for long distance when releasing only 1 cord, as it can then utilize rifling biconicals, but also easier short distance accuracy if I swap to releasing 2 release cords, which gives the immediate release/bola-like throw
This needs more testing
