getting new skis this year. trying to decide between the new armada alpha 1's or the new salomon twenty twelves. (or does anyone know how the line blends are?) i ski probably 80% park and 20% anything else so just wondering which would be better. and with the rocker/camber/rocker is it a good idea to get center mounted? im about 5'8" 185lbs and a level III skier. would a 170cm ski be okay for me?
