Replying to Recommend me new All Mountain ski's

Hey guys I'm in need of some new skis for the next couple of seasons, as my AR7's from like 3 years ago will no longer do the job. I need some all mountain skis, in the 166-171 cm size range. I'm a ski instructor, but other than that I mostly just ski park, but I will make a couple trips to the mountains this year so the skis have to be good for powder and mountain skiing too. Price range is like $400-600. Just looking for some suggestions on what would be the best skis. Thanks guys.
