I only keep a card when R1 if I am without a partner. Otherwise - I put my trust in my partner. That is what they are there for. I do try and keep track of setters and big hitters and where they are in the rotation.

I also do not use first names while on court. It's a personal preference. I just address players by number and coaches as "Coach". When I was a coach - I addressed officials as "sir", "mam" or "ref". I think using numbers and "coach" makes you appear more "objective" and official, whereas using names and sounding too familiar with players/coaches makes you appear more "subjective" and less official. JMO and I would never slam anyone who does use names if they are comfortable with it.
