Just saw the all new 2010 K2 Darkside Ski today and was really impressed at how light the ski was considering it is a 128mm in the waist. If you are going to AK and are looking for a big mountain AT ski the all new 2010 K2 Darkside would be an excellent choice all around. With K2 designing skins just for their skis it will make a huge difference in getting yourself up the hill with ease. K2 made a very wise decision in combining their AT/Tele line with their Alpine Backside Line. It helped them from having to double up on models which saves us all money in the long run and it also helps with not wasting materials as well.
