Personally speaking, a soft board matched up with stiff bindings is the worst combination possible. You better be ready to ride a really twitchy, really catchy board. That thing will really be keeping you on high alert at all times. You're just going to constantly be overpowering the board.
I threw my old Ride SPi's on my NS Evo one day because my Flux's were being warrantied. Terrible. I could literally wiggle my toes and the board was squirming around and trying to go all over the place.
