Park, mostly. I may go shred the Black and Double Black diamond runs here and there, but I've skied a true center mounted Alpha 1 and it feels fine to me. Just a bit fidgety.
Back to the point though, yeah, probably 70/30 or 60/40, park being the higher number.
"You put on your boots, click into your bindings, dust the snow off your skis, and head out for the chair, and it doesn't matter that you failed a test, didn't get the girl, or that your life is on a one way trip down the shitter, your world is right for the next couple of hours." - Jeremy Bloom
