I forgot my poles the other day. So I skied without them. It was fun, but my balance was way off, backseat. I had to pretend that I was holding poles to change my stance. The imaginary pole plant helped in the bumps and the trees. When I was skiing powder, I just wanted to drag my hands through it, that threw me way off too.
Other than that, once I got the hang of it, skiing without poles is super fun. Still wouldn't do it tho
