yes - both david and I nearly killed ourselves using one of Jax's baseball slings

Got pictures, design ?

So which is the release cord? The wider side?

I can't see how this could work as well as a standard split pouch. My split pouch has a very consistent fast realease . I have used slings with slower realease ( leather braid) and understand what your saying but I think this can be tuned out of your sling . Stretch and flexibility and pouch grip play roles .
This y pouch design still can have a delayed release . I also always let my projectile go from in between the release and retention . I don't hold the release in the flight path but rather cradleing the projectile .

As for captive realease. I have tried it on a few slings but find it makes it prone to tangle and am not seeing any major power increases.

I have made captive release slings before on a standard split pouch. They work however not in every style of throw. I imagine this is the same for a y pouch captive release. I haven't used this exact design but have used one similar where the ball passes through two strings.
The silent release appeals to me for a hunting scenario.
I have also tried a pouch release low on the sling where there is a mechanism that releases the pouch at its connection.
I got it to work but my design was heavily flawed.

I am more than open to trying out different designs but I always go back to my dyneema split pouch

i'm making one like this now. if it succeeds then it will be better than the Y-sling by being able to control the spin.

before using the new sling design i was alright with the old ones nothing bothered me because there was consistency.
if you want to understand what i'm saying about release friction then use a string tied on a stone and throw it instead of a Y-sling . throw it at a target several times until you feel comfortable and then use one of your regular slings. probably you will be late releasing but after some throws 10-30(depends on sling and thrower) you can compensate the release so you'll be on target.however the friction of the sling will still be there.

i used the Y sling for 1 hour so maybe it was a bad day with the regular ones which made the differences between the two designs more obvious.

first of all i'd like it if people could try it and put their thoughts on this. before trying it i too couldn't see a difference.if you pay attention you will feel it at release.

comparing the 2 designs: the conventional sling  has very nice external ballistics if you can control the spin and make it a rifle spin. but bad internal ballistics due to friction. any friction causes inconsistency.
it's like a rifled barrel with a bad crown.


the Y-sling has very nice internal ballistics smooth release(no friction), silent, but bad external ballistics: low spin that seems not that easy to control.
this is like a musket (with good crown).

if the other design works it will have the benefits of both worlds by adding a little complexity.

captive release is from what i understand there to ensure a release and not a tangling ,it also may help with reloading long slings Jax used.my sling is relatively short and works very well without captive release.
there is no extra power from a captive release. i also can't understand how it even worked on a split pouch(a picture might help)

i understand what you say about history, i hate complexity too.

The single cord bola would seem only to differ in that there is no projectile releasing. If I'm reading you correctly the release friction refers to the manner in which the stone rolls out of the pouch?

Assuming that's the case I've seen this as well. My fix if you can call it that was using good ammo. Friction and release delay becomes very obvious when you spend some time using good ammo then switch to random poorly shaped ammo. 

When I look at the captive release the difference seems to be that it both opens and widens at the moment of release. So I assume this let's the stone loose even quicker?
