Sorry to have been busy for a while..
Backpacker - it depends on the conditions that I'd be likely to meet. Late fall and winter here can be pretty desperate if you can't chop up and split larger wood. Normally though a hatchet would get you by IF you've used it a bunch. Add a 9.7oz saw like the Sawvivor and you'd be in good shape though - and have two tools.
My biggest concern with the hatchet is safety, because if you try to make it an axe by overpowering then it's no longer safe. Going slightly larger to the the small forest axe which can be used two handed with less fatigue, or adding a saw overcomes the problem.
I'm getting ready to try a light head with a longer handle to see if a long handled hatchet used two handed would be an improvement over the regular hatchet - like Neolyth over on Plainsman's forum.
Your best advice will come from yourself. If you can go out a few times after rain, and get a fire going easily -if you are safety conscious, if you choose your spot for wood rather than choosing a pretty spot with little wood, and so forth.
So under what conditions are you going out, with how many people, and will you be building shelters - as DWK pointed out?
