Not disagreeing with what else you said but if you want a revamped ar7 that would be the zero series AR8's
arv86 has a little rocker and slightly different sidecut.
If if you're looking for a pure park ski like peteythefish said arv 86 or chronic would be good choices.
The skis I listed were wider platformed park skis which personally I prefer in the park, more stability and better feel on rails in my opinion. But if you want a ski that is easy to whip around and light something in the 80-90mm underfoot range would be great.
