They didn't have a tank restriction and didn't use just 60 working psi. It was unimpressive. I could be wrong, and there could be a genius way to use them. But right now using a baseball pitching design seems to be the only viable option to keep a consistent shot while it being reasonable in the sense that you can do it more than once.

Neither of you are thinking outside the box
Take a 12" cylindar. lock it 1/2 way (mechanical lock like a fence latch). pressurize the cylindar. release the lock and see how fast the cylindar reacts and how far you shoot the ball.
oh, I'd put a hard stop on the rod so you dont damage the cylindars end cap
