I have demo'd Vertigo G3 Energy this weekend, - Sugar Bowl, conditions - a lot of light powder, snowing a lot all day.
It was a lot of fun, seemed to handle speed in deep tracked powder/steeps much better that my XScreams, but G3 has a strange tip that seems to sink in deep crud occasionally - I stumbled couple of times and one time fell down with my skis got stuck in big soft bump
May be a flaw in my skiing, but I have never seen this in XScreams ( I think SKIING mag review was mentioning this for some other Volkl models)
Also they did not foat well in deep powder. Other than these two things, they felt better than my XScreams.
I have demo'd 170cm (should I try longer skis? I am 120 lbs, 5'6").
