I have and shoot both, I have only been able to break 3 carbons in the last 14 years and I robin hooded one with a bh. I have broken that many wood arrows in a year. But I also don't shoot all that much.
That being said, it depends on what you want. If you are just looking for a good investment while you fine tune your shooting skills, I'd get a dozen lower end carbons that are matched with your setup and go fling em. You won't have to worry about if they are warped or the sealer is wearing off, etc. After you get comfortable shooting, then you can start into the wood arrows. They are a lot of fun and you can get a dozen for fairly cheap. And once you start getting into it, it seems like you'll want to start making your own. And then the "fun" begins.
Until I messed up my longbow, I shot carbon and Al out of it and they both worked great. I had a couple of wood arrows that shot good out of it, but they were a little lighter than I wanted for the bow. I shoot all 3 out of one of my recurves and they all shoot great, but I have the arrows matched to the bow.
