Back when I was in HS(about 7 years ago), we used to play with those red rubber balls, but they were the size of shotputs. It was incredibly easy to grip, and whip really fast. Before we played the gym teachers(2 males) would give people the option to sit out on the other side of the gym or play. Generally the boys participated and most of the athletic girls, but about 40% of the class sat out. The most fun I ever had playing dodgeball. These things came in insanely fast, but only stung if they hit the side of your face or man parts.
