But even that is nothing but a guideline. DEMO!!!!! Get a feel for what you like, and what length (keep in mind that if you like a pair of Dynastars in 155 cm, that doesn't necessarily mean that you will not like Rossignols in 165 cm, or Olins in 170) - and then buy them.
Is this an opinion poll or are you trying to get brand information to help guide your purchase. If this is an opinion poll maybe it could be set up as a pole and let people vote. If you are looking for information to help guide you to a purchase I agree with the above posts, we need some information about you and how you ski.
dude, just go buy what is on sale. all skis are about the same when you really get down to it, the only difference is which ones you yourself liek the feel of, the next person might think the exact opposite of you.
