Replying to Chronic or AlDente? in that order?

but seriously all kidding aside

Im about 5'9, 160lbs and have been skiing park on the K2 Recoil 179cm this season and have really liked them but i want a more buttery ski to add to my quiver.
I love the 179 in the recoil and understand that K2 measures their skis longer then others, thus I have been looking at either:

185 Line Chronic
or
188 Al Dente

I am a pretty aggressive skier and these skis will be a 100% park ski PERIOD
I have seen both skis in the shop's and I like the flex of both skis, I am however concerned with how thin the edges on the AlDentes look and the tip only rocker.
Any aggressive skiers who have skied either of these skis that would have some good input would be greatly appreciated!

Only 6 months till next season!
