Replying to Ar6's vs Moment jibs, vs Moment reno jibs.

So I'm pondering which ski I should get next year, and I'd really like some help.

I ski park 90% of the time, unless its dumping.
i'm 5'8" 170.

Last year i skied ar6's and loved them, but im looking for something different this year but don't wanna risk buying something i'll hate.

I love doing rails, and im afraid the fact taht reno jibs make it harder to lock on rails to pretzel(cause of the fact that they're rockered). Any ideas, suggestions?

I'm not too good on jumps but im hoping to get much better on em this year.
