Replying to K2 vs Filthy Rich

Ok so Im looking for new skis for next year and don't know what I exactly want but the skis I'm looking at all have similar details like rocker and width.

So it basically K2 Domain vs K2 Shreditor 92 vs On3P filthy riches

If anyone can give me some feedback about any of the skis above it would be appreciated.

I'm looking for mostly a park ripper but I go out west maybe twice a year or so for about 5 days at a time. I live in Midwest so we usually get measurable snow but it's icy and all hardpack so I need something that can survive that but not like an all mountain type of hardpack. I am more based on rails because decent jumps are rare in Minnesota. We got tow ropes so I lap about 100-150 laps a day so I need something to hold and be sturdy. I'm fairly lightweight so I would prefer a lighter ski with a low swing weight.
