I've been thinking about some AT gear as well, I haven't ever used any before, but I know it's something that I want to get into in the next few seasons. Big fat skis might not be so ideal due to the width, which could make it somewhat clumsy trekking up slopes, and the weight issue. A lot of people on TGR, where I have been doing my own research on the topic, swear by the Volkl Gotama's, 4 sizes (168,176,183,190) 105 at the waist, and a sidecut of 25.9m at the 183 length. Another ski that would be fun, wide and efficient in my mind would be the new Liberty Helix. That's what I have gathered, like I said, I have no experience in the topic whatsoever, but it does interest me greatly and I hope to get some gear in the near future.

You fritter and waste the hours in an off hand way.
Kicking around on a piece of ground in your home town.
Waiting for someone or something to show you the way.' - Pink Floyd
