I don’t want it stiff but resistance to twist . Stiff needs heavier ammo to overcome . I noticed this in all my trash slings

You are speaking  argumentatively in non-specific relative terms here. That’s the perfect setup for a pointless argument where neither side can even agree on what is being argued about. If you want to understand the effect of cord stiffness, design some experiments and try some ideas out.

The shape of the ammo is irrelevant to the stiffness of the cord.

The weight of the ammo is only one factor. Throwing lighter ammo faster will result in the same tension on your cords as heavy ammo... even if it is in the shape of a cube or a miniature Venus de Milo glande.

I have offered you a method to prove your assertions. Make two slings, then treat one to make the cords stiffer and test both with the same ammo, then tell us what effect the cord stiffness has.  That’s a much more efficient way for everyone to learn.

This is a untrue, unless you are treating and seeing the sling like a simple single cord pendelum.

But this is not what it is. The sling we talk about is made of two cords, with the projectile seated in the middle.
Varying shapes and sizes of projectile react very differently to varying cord stiffnesses. Even projectiles of the same weight but different shape. If you haven't figured, you need to get out and sling more rocks !

Counter-accusations? Really Jauke?  Are you just trying to pick fights?  What is the purpose of this conversation?

What I was implying is “stiffer relative to untreated paracord”. Is that not a reasonable reference standard?  Paracord is manufactured fairly consistently no matter who makes it, and it’s available around the world.

You are implying that I have no right to speak because I throw more tennis balls than rocks. I am not sure why you are picking fights today Jauke, but here’s the thing... I don’t have to engage with you, because in a week or two, you will have completely forgotten about cord stiffness and will be obsessed with some other esoteric element of slinging that you are just as convinced is the “one trick” to slinging.   It’s pretty entertaining, but I find it difficult to take your theories seriously sometimes.  Go do some experiments, present some evidence, and then tell us all about why you think X is so critical to slinging.

I prefer to measure my sling stiffness in radians per gram per smoot when slinging bananas.  If I am slinging larger ammo like baby dolls, then I switch to radians per pram instead.

I consider myself more of a postmodern industrialist, but only when slinging bananas.  My self identity changes with my ammunition.
