jester pro might indeed be a bit overkill...
i'm about the same height/weight as you and i've had jesters on my designated park ski last year and i was very happy about em.(also have em on my pow ski)
the jester pro will probably be a little overkill and personally i think you're better off saving the money...
other options would be the STH14 or 16 with driver toe (or the same models, ie. atomic ffg16)
4frnt/ tyrollia deadbolt/peak 15
or especially for park riding, the look pivot 14
personally i've also been really happy about my older look PX bindings but other NSers seem to dislike them.....
personally they've served me well for almost 4 years, only when snapping in i sometimes need to pull the heelpiece up .... and they're relatively cheap when compared to similar bindings
