All mountain ski suggestions

hi.

recently my binding broke and i discovered that both of my skis have rotten cores to some extent. one is ruined, the other is still useable, but i'd rather not risk using it until it snaps while i'm skiing.

in the past i always wanted to have a ski which i could use for a variety of things; park, powder, trees and cliffs. i bought the ar6 and they were pretty good at what i wanted them for. presently, they are dead.

now i'm looking for a ski with these properties:
• long lasting & very durable
• good float on powder days with 20cm+
• excellent stability on any type of snow, also at very high speeds
• able to manoeuvre in crud, tracked out/crusty pow, ice and whatever else the weather throws at me
• stiff/not too playful
• available in 190cm+

any serious suggestions will be very much appreciated. +k
