parker,don't be gay. you're the one who asked the question and I gave you an honest opinion, i think if you're gonna ask for help and someone is nice enough to provide you with it, you should be greatful.....not a cocky piece of shit. I've worked in a shop for all my life, take my opinions for what they're worth to you. If they're not worth anything, then don't bother posting questions like that.
I have a nice fat powder ski in a 180, a more than sufficient size for my weight in deep snow. If you're getting a decent mid fat and you only weigh 140, even if you grow you'll want a 169 for the park. If you find them to be unstable as you're weight increases find a nice used pair of XX in a 180 for $250 cdn....
