As a female who played ice hockey on both a women's team and a men's "pickup" league, I can tell you females don't stand a chance against men in that sport. I played in a "no check" league (no intentional body contact) with a bunch of guys, and would not have wanted even accidental contact. Guys are bigger and stronger. I'm fairly small but could out-skate most of the men in the league so that kept me safe. We were really careful not to run into each other because we all had to go to work the next day, but collisions happen. That said said, a tranny league is hysterically funny and I think I'd pay just to see the spectacle.
