I worked a lot of slo-pitch years ago back in CNY. Even did games when they had unlimited arc. I found it hardest to call illegal pitches on "flat" ones as you don't have much time between when you believe it is too low and when the pitch arrives. A verbal call is all that is really needed when you work alone. I also often wondered if the batters even paid attention to me. Good luck with trying to get your umpires to do it the way you want.
