I'm sorry about not being clear. I'll try again. It looks to me as though most if not all of the skis are being built flat (smooth or straight) across the width (on the top) of the ski. My question is a 2 part question. First, is that the case? If the answer to the first is yes, than why?

Has anyone tried to put a shape (in the width) to the skis. I know a little bit about molds. Does a profile in the width create too many problems with creating voids?
