As far as the women players, Ga Young Kim is a very good 3-cushion player and would have to be the big favorite in a women's event (I've seen her play). I understand she was trained by her father & for the first 4 years was only able to play 3-cushion before she started with pool.
Melissa Little has also played around with the game, but would not be close to Ga or maybe Jeanette. But she loves it just the same & was signed up to play when they tried to hold a women's 3-C event in Fl, which was cancelled due to hurricanes.
