Hate this Board!!!...(little long)

I think the length of time you wait to blow a jump is highly dependent on the level of game play and flow of the game in question. Middle School game with 30 jump balls = hold the whistle a little longer. Frosh girl with 15 jumps = let them play a little, but not as much as middle school. At higher levels with bigger and stronger players, letting the players fight for a ball that is held is inviting conflict between the players. How many fights/verbal spats/staredowns/etc. happen after loose ball/held ball situations. Quite a few. A quicker whistle for the held ball can defuse some of the emotion here.
