So awhile ago in late october I got my first pair of twin tips, the K2 sight in 159 cm. I'm about 5'6" and 135ish lbs, and I'm not sure if the skis I got were to short, even though the guy at the store said they were the right size. I'm worried because I know that they will ski even shorter than 159 because of the twin tip and the slight tip rocker. I am an advanced by wisconsin standards and int-adv. (probably about level 7?) by out west standards, who skis mostly in wisconsin and the UP where everything is pretty easy, but I will be going to summit county for four days in late march/early april.
To my understanding, ski size is determined mainly by weight and skill level, and I am worried because one of my freinds who weighs about 10 lbs less than me got 169 cm skis that aren't twin tips and are fully cambered, and he is a much weaker skiier than I am. He is also about 4 inches taller than me.
I'm also probably going to grow another inch or so and keep putting on weight (I'm 16 years old) and I'm worried these skis won't last for long, and will suck because they're too short.
