Driveline Smash Factor machine balls

[GopherState]

Our club has a 3 wheel Hack Attack that rarely gets used. Our facilities guy says we can only use Baden genuine leather balls in it by the hard balls seem to hurt the girls hands quite a bit and it’s accuracy is inconsistent to the point of it throwing one wild and nearly hitting girls.

I’ve been interested in trying Smash Factor balls through it. Has anyone tried using them through a Hack Attack?
