We use flat nylon straps. Similar to the flat nylon strap on ratchet straps. We have different lengths for different situations. I keep a short 3-4 footer in one pocket of my coat for a one person tug on a ski loop, and a 15-20 footer in the other pocket for the real stucks that need 3 or 4 or more to pull. I have used a snowbunjie and they work, but I think it is not so much the "bunjie" effect as being able to stand up and get some leverage when using the bunjie/strap. There are situations where the bunjie is better, but for my money (free), and the convenience, the strap wins as it will easily fit in your coat pocket.
