What lenght should I get?
Any help is appreciated. Thanks.
It sucks to bend a pole in the middle of a great day; go composite, carbon fiberglass types. I once had mine leaning against the back of the car when I pulled out of the spot. car wouldn't go. I got out and looked behind. the poles were wedged and the car wasn't moving. they're strong enough. Steeper terrain with deep snow = slightly longer pole, otherwise the formulas are fine.
Base layers (brand irrelevant, look not so important)
Pants (eg, maybe not top brand, perhaps still Gore Tex)
Skis (you're just gonna wreck them anyway)
