Just FYI - our local kids rec league pays $30 for HS level games (boys and girls) to experienced officials. We work two or three games in a shift, all with a two person crew. Games are 7 minute stop time quarters with a 3 minute halftime and teams get four 30-second timeouts for the game, so the games go pretty quickly (also 15 point "mercy" rule - no back court guarding). We don't switch on every foul, but we do switch on virtually every shooting foul. On non-shooting fouls, we switch if it "makes sense" - meaning if the positioning of the refs when the foul was called makes it more logical to switch (I think you guys know what I mean). We call this "convenience mechanics".
Sure - we get complaints that the refs are favoring one team over the other. However, those complaints usually come from both teams.
Oh yeah - since we don't really designate a referee and an umpire, I always ask my partner just before tip off if he wants to throw up or have the runs.
