For big mountain longer is always better. If you're 5'9 you better be a pretty agressive skier to handle 188s, however, If you are into killing huge powder fields at close to 50mph those are your skis. If you are more of a billy-goat and like quick technical turns in rocks, and trees you want the shorter ones.
