hmmm
What you could do is use your invaders for park stuff and jibbing and just not the big hits.
Then get a stiff midfat ski for park (100 or so in the waist) if you are comfortable with wider skis, which you will get used to easily, I ride my Bacons in the park and they are a blast, a bit harder to spin, and I'm not great at park so take what I say with a grain of salt haha. You would also be able to use this ski for all mountain and even a bit of pow assuming you don't mount it too close to center.
Then since you'd already have a jibbing/park/urban ski, and a midfat that can handle big hits, and all mountain you could get a pow only ski, and since you already have 2 other skis you could get a reverse sidecut ski for pow, although I'd only reccomend reverse sidecut if you already have 2 other pairs of skis, one being a midfat. So you could go ARG's or Donner Party's which would be great in pow.
This would be expensive though, but if you have the money then having a 3+ ski quiver is really nice, if you can't get 3 skis you could always go with like Hellbents, and then a stiff park ski with a more narrow waist, because the Bents would be able to ski all mountain if you really want to, well at least more than a reverse sidecut ski.
