Woah! that is a pretty slick sling! I dig the Aesthetic.

I feel like life is pretty asymmetrical.
Does the shape on that help with throwing tennis balls specifically? man, Now I want to play Tennis where you serve with a sling.
Ah, good to know that trains don't stay on the proverbial tracks around here. It's a good thing my brain works that way too!
It works fairly well with other ammo too.
For example, this guy uses it to great effect with golf balls:

The idea behind the asymmetry is that the ammo stays securely in the pouch because of the pocket, but the flat side moves out of the way for a fast, clean release.
