yeah, its a step up in stiffness from the WWW which is comperable to the artifact.
and for park, at your weight, i'd say no bigger than 157, if you want something to hit jumps and rails, then a 155/156 would be best. i'm 140 and ride a 148 for rails, a 151 for kickers and rails, and a 153 for pure giant booters/natural terrain. well that is if i had three boards, thats what size they'd be and for what.
That thing I do to escape the world and have fun with my friend
