I don't give a flying **** about the crowd, the perfect time to play paintball is the perfect time for the players.
some people would argue that what's right for the spectators (tv audience) is what's right for paintball. Of course those people would be the benefactuaries of someone like say... Dick Clark.
If Dick Clark (or any other media mogul with money) wants glowing paintballs and night games, and is prepared to pay the league and the players for it, then it'll be 'right' for paintball.
Me personally, i like a nice sunny day, not too hot mind you with a gentle breeze. But then i'm not really all that fussed about the TV thing.
