Not affiliated with this, and ironically I'm a current pickleballer and former shitty high school tennis player that'll be starting a kid in tennis soon, and on the off chance he likes it, I'll probably get back into it somewhat so I can hit with him.

So this seems compelling, probably worth it if it doubles the useful life of practice balls without having to go pressureless. That said I know stuff like this has been done / tried before.
