Replying to Newschoolers, I call upon your knowledge.

Alright Newschoolers, I have an issue. I've outgrown my old and destroyed Coreupt's and now I'm shopping for new skis. I'm 15 so my dad has to approve everything. The issue is, he can never admit that he's wrong. I found a pair of skis I really liked ( Link is here ---> http://surfaceskis.com/hardgoods/time-series/no-time/index.html ) and he claims they are "too skinny under foot". Yes, they are a skinny ski, but my question to you guys is: Does having a skinnier ski under foot make it easier to catch edges? My dad thinks so and says i need to get a fatter ski, which I really don't want to do. Thanks for the input guys.
