I bought a pair of Ground Control boots as a first try at alpine riding. I'm pairing them with my inner boots from my Neidecker Talon soft-boots on F2 Intec bindings on top of my Swivler riser plates. I've worked with Donek to spec out a 175 Flux, 23.5cm waist, 9.5-11m SCR. Angles are F:45, R:36. Shown on an old Head Intelligence board.
I'll post later in the year how well they perform.
