The last two well known, successful girls teams from Mt. P were the (Lady) Ice and the Fury. The girls from the Ice were mostly members of Wando's state championship team in 2004 and are now indeed juniors in college (the team featured Kelly McGinty from CofC, Lou Hudson from Clemson and CofC, Greta Hewitt of Newberry, and others who decided against playing in college). The Fury girls are either seniors in college or just graduated last year.
The Impulse (year younger than Ice) was mildly successful with a bunch of state finalist placings and decent records in Premier League, but never placed first or made it to regionals. I'm not sure about beyond them, but the end of Ice's reign heralded the success of Greenville Futbol Club's U18G team (that at points played both Lindsey and Hailey Beam, I believe) and the Impulse lost players to Andy Grist's Carolina Girls U17 team (featuring Danielle Jordan of CofC, now a sophomore?).
At any rate, those are the last truly successful MPSC girls team that I've heard of or from and all three (Impulse, Ice, and Fury) were originally Hungryneck Soccer Club teams. Any others from younger teams and you have to ask someone else.
