First of all, its not like your riding big skis, true they are a little bit long for your height, but nothing crazy. Part of the reason you think you can ski better is because they are a lot more stable riding and landind and such. Most people will ski best with a ski that is 70s to low 80s, unless its big mountain, than its gonna be a bit longer. Personaly I think tricks look best with longer skis, but you should ride on what ever you feel best on.
