I like using the lynx levelers because they are light weight, and easy to store in their own little bag. Also, I don't have to worry about them taking on water or insects; when you take them up, you can just clap them together to remove all the "stuff" that accumulates.
I can't say they don't "rot" like wood, because the plastic is UV sensitive and will degrade over time; so it's just a different kind of rot. They will eventually need to be replaced.
All that being said, I keep a decent stock of scrap lumber on board as well; you just never know what you're going to need!
