NOWs increase your board response. JF spent quite a long time on them and they work. They were BA's favorite binding he rode last year.
Just a note, the Peacekeeper is basically the replacement for the Gyrator where the Ultra is a back country intended tweak of a Turbo.
Good reference point. Still don't know which to pull the trigger on... What should I do, Nivek? 58 twinish set back pow/freestyle more versatile slayer with all mtn-capabilities, or 59 directional pow raper slightly less versatile pow-specific board with minimal but still decent all-mtn aspects
