If you ever wondered if you can set up a Spinn Twinn in the snow. Hendrik Morkel recently created a great post on his site Hiking in Finland. It shows lots of pictures and describes how to do it. He goes over what types of stakes to use, how to support the poles, what types of knots work, and how to cinch it down for storm mode. In his blog, he covers the benefits of tarping and shows multiple pitches in all seasons with an interesting home made bivy made out of tyvek.
