Besides 220lb glides on powder and your not dragging the sled the entire time.

You have never been in actual snow have you.

Firstly, nothing glides on powder unless it's on a steepish slope.

Secondly, sleds have runners, which would dig into power and make it harder.

Thirdly, there is fuck all powder at the poles - it's windblown crust and ice. There might be some fresh snow, covering lumps of ice and uneven slabs.

Suggesting the weather wont be a problem is extremely naive. I have very high quality outdoor gear, and if the weather turns it's job is to help you survive. A storm at one of the poles could kill.

You are hilariously clueless tbh, but that helps explain your stupid comments I suppose.
