Whatever style you buy, you will soon realize the benefit they are. In rocky terrain, I have broken or bent all the high end poles and will settle on moderately priced sets.
Straps are also a benefit as you can use your hand without losing the pole for a variety of tasks. Don't forget to match your baskets to the terrain you expect.
Trekking poles, snowshoes and an elk tag are about as good as it gets.
