What park ski?

So I am wanting to get a 100% pure park ski.
I've looked at so many but its all narrowed down to pretty much fujis 179 or scratch fs wrs 181.
I was also looking at invaders, but it seems like a brand new 179 size is very very hard to find.
If anyone's selling a pair in a good cond., I will consider it maybe.

I am 5'8, 130 lbs, not a bad skier.
I don't do rails a lot but I do sometimes.
I will be mostly hitting kickers with these skis.
Which one should I go with?

Oh and I am pretty tight on the budget so anything like ar6 or dumont is out of the range.
