The new Fischers are the ones I want, but I am not sure how different they are from the Spiders I already have... mine have metal edges in the front and the back of the ski. I've had these for 2 years. They are much shorter than my previous skis, which took some getting used to. The old ones had the metal edges along the whole side.
I second the opinion to get snow shoes, but I find that unless I am doing some serious climbing, on big hiking trails, I just don't get the same kind of "sweat" going when i snow shoe. I can x country ski on flat trails and be really working hard, but snow shoeing on flat trails, tends to be like a fast walk for me. There's nothing wrong with that, but for me, the energy expenditure is quite different. I like snow shoeing, because I have trails in my neighborhood and I can do it out the door, or in the many conservation land trails around here. I also like the fact that in some of the x country ski areas we go to, we ski in the morning and then snow shoe in the afternoon, which seems to be a good combination for me. If I stop for lunch when I ski and then go back out, I am toast and my skills degrade quickly. Often, I end up skiing until 1-2, with snacks and have a late lunch, because I have learned the hard way! If I stop and eat lunch at noon and then snow shoe, I am fine (though tired).
