When you update with your height could you also give more info on what ski you want. You say "Big Mountain/Powder" but will the ski only be used on blower powder days, or does it need to handle chop? Do you want a ski that is directional or has a flat tail for support?
Will you be hucking cliffs, if so what size?
What is your background/training, ever raced?
How aggressive is your style?
Do you prefer a certain flex in a ski?
What skis have you been on and liked/not liked?
these and anything else you can think of will help people give you a better and more accurate reccomendation.
