I'm looking to purchase a pair of skis, and they have some Head Monster 72's at Levelnine for a good price. I'm trying to decide if they would be the right ski for me. I ski almost 100% in NC and WV. I'm 6'0" and 180 lb, and like to ski mostly high blues and blacks, though I've never tried double blacks. Do you think these skis are right for me? Are 177's too long?
