Should I get the on3p jeffery? Hi I'm 5'7 125 lbs, should I get these? I'm an advanced skier, and want a ski that is VERY light, can ski powder, and rails/boxes and land jumps solid, but remain playfull with carving ability. Is the on3p jeffery the ski for me??? If not, any other recommendations on light park/pow skis? Any response helps thanks.
