Replying to LINE Chronic vs. Stepup vs. Afterbang vs. Traveling Circus/Anthem

I was riding the Stepup for the last two seasons and i think it's a great ski. But now i was wondering if another ski would be a better fit for me. I ski mainly park and got a second pair to ski powder, so it doesn't have to be very versatile. I weigh 185lbs and i'm 6'1 that's why i got the Stepup last time and not the Afterbang (i thought i'm too heavy for the Afterbang, but i might been wrong). I ski mostly rails/boxes and when i hit a kicker from time to time, it won't be bigger than 20-30ft. So which of those skis would you recommend?
