PB&Js are STIFF, stiffer than my Jmos, and much less flex than anything line (excluding their freeride skis) makes. They aren't really designed to a be a park ski, more all mountain ripper. You can think of it as bigger vice or smaller bibby depending how you look at it, same ski design. I don't think it would be the best choice for 70% park, maybe for 70% all mountain though.

Where are you skiing? I'm not a huge armada fan but people seem to love the Alpha or Aldentes for a wider park ski. Faction definitely has more than one ski for park/mountain in the 90-100mm category, check out the Soma or Wednesday. Although its a symmetrical ski, ON3P FR's could probably get around the mountain fairly well, they have a ton of rocker and a very substantial core. Most companies make a 90ish park ski with rocker/camber/rocker these days anyways, you shouldn't have much trouble finding a good ski.
