Replying to Ski specs

ive been wondering lately about ski specs.
why is it that for most skis, the ski only gets longer, but not wider?
why doesnt the si as a whole increase its proportions?

with an example: the rocker of the hellbent is 2cm i believe?
proportionally the 169 hellbent will have a way steeper rocker than the 189 hell bent.
o wait, im stupid, the bents have a 40/20 rocker right? ok, but you get the principle?

or with the width of the ski. the 169 is just as wide as the 189. a person being 169 tall will have a proportionally fatter ski, than a person that is 189 tall.



why doesnt the industry create skis proportionally? supposing a company said, the ski has the perfect proportions at 175cm length. lets say its a park ski and its 109-82-109.
the 165 ski could be 106-79-106 so they will have more or less the same feel for a person that is 165 as it does for a person 175?

do you get me, i know it may be a bit confusing :D? i think this is a good idea though.

what do you think?
