I also use the Vargo ti shepherd crook stakes. Either get the kind with fluorescent orange tops on them or paint them yourself (you'll have to repaint at least annually). I used to lose one every trip! A rock or two may be needed for reinforcement when it's extra windy or (as often happens) you can't get the stake all the way in (if it isn't a rock, it's a root, and stakes won't go through either).

The problem with the Easton aluminum stakes is that the tops tend to pop off. I haven't found that they hold any better than the shepherd crook stakes, either.
