I make no mistakes...my hair like my skiing is a site to behold (jk). To answer you question you have to ask yourself, how good of a skier do you want to be. If you are satisfied with being average, then stick to you generic beginner ski (otherwise called twin-tips).
But if you want to ski fast, and impress the ladies (afterall that is why we ski) then you need real skis.
My Rules -
Nothing under 195cm on powder days...wide and limited sidecut
On groomers - I like short and stiff with risers
In moguls - i like narrow, straight with a stiff tail
For my hair - I only use organic products
and I ONLY use a salt water filtration system in my hotub...keeps the ladies smelling nice.
But seriously...this site is awesome...keep up the stoke!
I check in once in a while - peace out
