S-place, didn't you ask about Chubbs once before in the last few weeks ?
Ok so I answered your question with a question, so here is the best answer I can give you.
Based upon my having a pair of first generation Chubbs, they can be the only ski you will need for the trip. When I started skiing them as my primary ski, I got all kinds of comments the most frequest having to do with how wide the skis were.Mostly from the "lifties." Not a problem anymore more than five years later.
Just remember that to get the most out of these easy flexing skis, remember, that they do have minimal side cut,so you will need a little forward pressure on the tongues of the boot as you lay the skis on edge. They should bend fairly easy so you will be able to easily "arc" the ski.
Also become a two edge skier. Up hill outside edge and downshill inside edge need to be happending at the same time. Try for similtaneous edge change, by using an ankle or knee rolling technique. Be more conscience of what will become your new up hill outside edge. The downhill inside edge will almost take care of itself.In powder, lose snow, gunk, crud [cut up snow] equal weighting of the skis becomes very important.
These are not fast edge to edge skis, though I think you will be surprised at how nimble they are for there lack of side cut. So if you are planning some NASTAR runs, just enjoy yourself. Do put some F 4 or NotWax on just before you race. Remember these skis have a lot of surface area, that you can use to your advantage if the course is not too technical or requires a lot of skating at the bottom. So ski a flat ski whenever possible, be definte in your edge changes, but be smooth as possible, and turn early, very early.
As for the bumps, I have heard both negatives and positives. If you are skiing the 180 or shorter ski, you will be OK, but not great in the bumps. The 190's just are not good in bumps, just too long and too slow edge to edge.
For everything else, they are a great ski.
So practice on them before you go out west, and they should be fine for the whole trip.
