I'm 6'2, 180 pounds and have skied very aggressively on my Dukes both in bounds and with touring without any problems. With that being said, they are a little heavy, and the lever for touring is kind of a pain, but in my mind to complain about that is reeeally splitting hairs. Why do we expect to have shit always work perfectly?
The new Salomon/Atomic one is getting a lot of hype for next, but after looking at specs and whatnot I think my next pair will be the the Tyrolia. They kept it more under wraps so there isn't as much hype around it, but I'm excited by it.
Here's a sweet little look at the new Duke for next season, the Guardian, and the Adrenalin from the boys over at Early Ups.
