Irongoober have you studied how Luis throws ? It seems you are forgetting the final flick in the wrist to my eyes.
I find this final turning is essential. I think I saw Jaegoor doing it too. It makes the release spiral very clean and increases accuracy tremendously
He brings the sling forward like you are you doing, for a spiral release, than while he releases at the end of the throw, he produces a very sharp and quick turning of the wrist and forarm. This prevents the pouch from turning against the projectile like it does in your last frame photo.
It works for all slings in my experience, floppy and stiff.
Of course. His style fascinates me. I've probably spent hours looking at his videos frame by frame.
But if I look at mine, my wrist is similarly pronated (palm down) after the throw. Since the release of the projectile only takes ~16 ms (4 frames, 240fps), the position of the wrist when the projectile is loosed is the only thing that really matters. For any pronation/motion of the wrist to matter, it has to happen before release. I suspect Luis is similar to me (because of biomechanics) in that his pronation happens mostly after release.
The tipping of the pouch changes a bit depending on the style of sling, both the pouch and the retention loop. It is more rifled if I use a split pouch, and using a dual finger loop is better than a single loop. I've checked this using 240fps. Of course, this is just for me, other peoples' styles could end up with different results.
