I felt the 14 was stiffer but otherwise Niveks review is spot on with my experience. Mid flex hybrid camber twin, like you said on the park side of all mountain freestyle. Depends where/what you like to ride but it's a solid all around board.
Czoid what boards are you looking at? I've been on the majority of their boards over the last couple years, haven't spent enough time on any to give a full review but could at least give you an idea of flex.
