you guys have to remember that ski length is more associated with your weight! obviously height is taken into account because of leverage, but what is leverage without enough force/power to lever it?
anyways, I am 5'10.5" and around 135, yeah I'm a twig, and I ski 177 chronics. my legs are strong because I'm athletic and rollerblade, but the stiffness of the chronics makes it a bit hard to pop, so the sense that I've made of it all is that the lighter you are, the shorter and POSSIBLY softer you want your skis, and the heavier you are, the more you are able to control stiffer, longer skis..
