im pretty shure this is a girl. and anyway, id say go with head high, especially if the ski your looking at is lighter. cause you are center mounted, and that you have 20 Cm less running area (twin tip), twin tips always feel alot shorter. plus, a longer ski is easier to land on. honsetly, there isnt anything to gain by going on the shorter side (you may feel like you can huck stuff around faster), but there is a ton to gain by goin longer (speed, stability, smoother carving, better looking, ect). id say go to the top of your head, and if your still growing, skin them til they are nose high
i looked on google but all i could find was 3D Animation porn-sxmarty6
