a good skier will be able to ski anything, but they'll have their limitations. if you have super soft skis, you wont be able ski them very aggresively. OR is you are not an aggresive skier, or don't weigh very much, a super stiff ski will not be able to flex enough and you wont be able to turn the ski like they should turn. If you're a crappy skier, the only thing that will make you better is to take lessons, or just ski a whole lot and ask for some tips from good skiers on the lifts. the best equiptment in the world wont make you ski better if you're always sittin in the back seat, arms flailing all over the place, etc....
