I think the CG fin is a game changer but is it significant enough to influence your ski size selection?
For this question assume you were on the bubble between sizes and it’s the same ski in two different sizes.
A) yes, with a CG fin I can make a smaller ski more stable.
B ) yes, I can make a lager ski turn easier.
C) no, the CG fin will not influence on what size ski I choose.
Disclaimers: 1) yes, yes, demo first is always the answer. 2) yes, I know the “experts” say always size up.
