it depends on what you mean by run short cause everyone measures their skis differently my friends has the biggest invaders i think theyre like 171 or something like that and theyre the same size as my 178 fujatives but K2 meausres their skis by where the ski touches the ground so i dont think this has helped you at all but this years moships are really flexible so keep that in mind if you weigh alot of are tall or are a good skier id suggest the 182s
