A sports sling, which is convenient to throw only balls, not stones. Why make the sling heavier?
The video used a universal sling petal in the color "Hornet" (orange + black paracord)"+ inner layer with metal balls to increase the weight of the sling. The total weight of the balls turned out to be 20 grams. +sling weight of 30 grams = 50 grams total sling weight. I make standard braided slings from paracord weighing 25-30 grams. Weaving and additional stitching of the sling in critical places creates rigidity and adds better control over the ball when throwing, and an additional mechanism with the insertion of a string with balls helps to accelerate the light ball faster and more accurately bring it to the long swing and the starting point of acceleration / acceleration of the projectile. This is the first trial version, I just started experimenting with reducing the weight of the sling without increasing its sail capacity. In the process, it will become clear in which areas the weighting helps, and in which areas it will interfere with the work of the sling. One thing is clear, such a sling is suitable exclusively for throwing tennis balls and light protective projectiles, and therefore is not suitable for throwing stones.

To increase the accuracy of the throw, I would advise you to try throwing from a braided sling in a geometry similar to Balearic. Smooth expansion at the basket and gradual narrowing to the tail and finger loops. This geometry of the sling does not overwhelm itself when the ball is dropped, and it is much easier to shoot at a target with such a sling. But of course everything is individual, you need to fully customize the sling for yourself. To make the loop comfortable, the most important thing is the dropping knot by which we hold the sling. The more we try different versions of slings, the more details we discover that can be improved and make our throwing better.

I was lucky to work in a shooting range with very good archery athletes. The guys are members of the national team, participants of the world Championships and the Olympic Games. Professional athletes-they explained how to build their workouts, keep a diary of training records and their results. In this way, it is possible to monitor and gradually improve shooting techniques and the constant adjustment of shooting equipment. I think it works the same way with a sling. For accuracy, in my opinion, you need to keep your own statistics. Not single shots, but full-fledged series of a large number of shots for the result. Record them and analyze both the equipment and the equipment we use.

To identify errors and work on them, we need the most identical shells. Tennis balls are great for this. You can practice with them every day at almost any venue.Throwing stones is certainly very exciting, but not everyone has the opportunity to find the same ones and have the opportunity to train with them regularly.

Good accuracy!
As far as I remember, Andrew from this forum also uses or has used weights for his leather pouch. But it seems he only has these materials on Instagram; I couldn't find them on YouTube.

[a thin sling makes a sweep and knocks the ball off a straight trajectory..]

I have seen the same thing when throwing really slow with very light whiffle balls.

Need tension on the release cord to make it whip open and out of the way. Tension comes from a hard throw (centripedal acceleration) or a heavy projectile.

Also helps to have a smooth pouch/release cord transition I think…just in case there is contact.

Cool video!  I totally agree with the heavier pouch feels much nicer to throw tennis balls. That has been my experience too.

All my descriptions in this topic are only about throwing a tennis ball. I do not consider stones and other compact and heavy projectiles in any way for throwing slings with additional weights. This will not only not give accuracy, but will also interfere with the acceleration of the stone.

Analyzing the behavior of a thin light sling and a balearic..I do it with the same technique and throwing style. And with the same errors, my performance is 2-3 times higher for Balearics and other slings that have a woven body with a smooth extension to the basket. They also allow you to make a very smooth and controlled grip/knot. If you make a knot on a thin sling, it will either be very small or very large and rough relative to the body of the sling itself. And it is the release, the purity of the nodule from the fingers, that suffers very much. But again, I'm only describing my feelings and throwing technique. Another slingerist may have a different anatomy, hand size, and finger thickness, which allows them to throw thinner slings. And that's okay. We're all very different.

I'm probably lucky. When I first started slingshot throwing, I was engaged in reconstruction. And it so happened that my first sling was woven from nettle plant fibers. Subsequent slings were also woven.  And I quickly managed to learn how to hit large targets relatively well. When I tried, out of curiosity, to make thin slings out of paracord and thin threads, I was surprised at how wide the projectiles spread, and how difficult it was to hit the target. Of course, it's easy to make them, but this is their only advantage. And when I see how the guys despair that they will not hit the target, but continue to stubbornly throw balls from thin paracord cords, I am surprised at such persistence. All you need to do is make a pair of braided slings and compare them. This creative search will allow you to understand the difference between the work of different slings and, as a result, will give you new knowledge and skills and the pleasure of throwing from the thicket.

It seems your statements are becoming too categorical. I can agree that single-strand lines are HARDER to throw, but I don't agree that they are generally WORSE in terms of performance.Furthermore, thin webbing can also be flattened like a noodle, which will reduce its deflection due to the stiffening rib. For example, by using dyneema and rolling it out, or by sewing two cords together, as Sarosh did.

To keep the discussions constructive and not based on feelings, I suggest moving on to clear metrics.
For example, here are measurements from a typical workout at a relaxed pace with a thin strap and a ball. It shows the average speed, and below is a stability graph.

Speaking of accuracy, you can check out my Instagram (the button is under the post) and watch a few relatively recent videos. And don't get me wrong, I'm not boasting about excellent accuracy, my experience is only about two years. Another example is the Pansling. It has good accuracy and power with a single-strand sling (balls and stones).
What I mean is that if you compare the overall accuracy and grouping of a sling, I don't see a HUGE difference in performance, considering the design alone.

The slinger's experience has a greater influence.

p.s. Oh, and here's another one, for example, Primal Slinging. (mostly stones)
p.p.s. Ah, I just remembered another example! @Andrew_slings (balls)
p.p.s. And yes, how could I forget! Mersa (balls)

I'm also talking about throwing balls, not stones. The results are completely different with stones.
Just take a look at the Instagram of the four guys I mentioned above.
