2-Man or 3 -Man?

[refnrev]

For HS games, do most of you do 2 or 3 man crews? Around here it's 2 except for the largest schools for boys or a game that is for a conference championship with a history of strong rivalry. All are 2 for girls games until play-offs. That was a real change for me when I moved last year because where I lived before it as all 3 man. No 3 whistle, but 1 whistle and two flags. I find it strange that schools use 2 officials for a boys soccer game with 22 players on a 120 X 55 yd field, but use a 3 man crew for girls basketball with 10 players on an 84 X 50 ft court.
