This whole center of gravity thing is horse shit. Look at olympic gymnasts. Those bitches can flip across the floors like fucking ninjas. Technically, women's center of mass (lower than mens) is better for spinning because it more centered relative to their height. Regardless, it's not like having tits makes you spin wildly out of control when you take to the air.
The only reason women don't progress is because they're not consistently viciously competitive like guys are. Sure, if theres one girl who's an anomaly who's intensely competitive, she'll progress to where she can beat the best girl. But where does that get you? At a smaller mountain, if a girl can do a 3 and front 2 out of a rail, boom, she's the best skier on the mountain and theres no need to progress any further.
It kind of pisses me off when competitions have equal prizes and guys are hucking their meat trying dubs on a 70 foot jump while first place for girls is determined by who had the cleanest straight air on the 25 foot sidecar. Another example is how at my local hill, to podium as a girl you simply have to enter the comp, and to win you just have to slide the whole rail, and then you take home a brand new pair of skis. meanwhile, theres 40 guys competing, and busting their shit trying 6 on's and 3 swaps for the same prizes.
blows my mind
