Forgive me for stupid questions. I am new to all this "racing stuff".
I see many rasing skis FIS and NON-FIS. What is that?
Q#1: What is FIS?
Q#2: If I plan to race in Nastar do I need FIS or not?
Q#3: If I race in "Fun Race" event on my mountain, do I need FIS?
Q#4: What are cons and pros?

Thank you kindly
