The best all-mountain ski is the one you are on, provided you can ski all of the mountain on it. I think this is a bad question. There is no best ski. It's all opinion. Volkl does a great job, so it's probably not a bad ski. I got K2's for free one year. That was the best all mountain ski I have ever had. Geeze, I hope I get some more free skis. I have not skid the best ski made in a few years. 
Sorry, I had to have some fun with this. No one has ever given me Volkl's.
