Yes, you're correct. Because I'm pretty sure I could keep up with a group of people who have never skinned before with that on my back. Plus it will be good training. If I'm going to only skin 2000-3000 ft. of vert in one day I would like to have some other challenge to get my body working.
Hey I've skinned before! OK it was 15 years ago, but it was in Austria ... and I'm fat and out of shape now. How much to carry me up? ;-)
