I cant speak towards the FKS but the Attack 13s are my favorite binding
I've had attacks, griffons, barons, salomons
Nice wide platform and i think they're the easiest to get into and out of with out issue
Plus you can get em on 4frnt for super cheap now with their coupon

code: GET4FRNT30
Should bump em down to $147-ish
I would call and ask for free shipping since everyone else and their brother offers free shipping over $50
Hope that helps
