I shoot alums, carbon and cedar. Depends what I can get to work. For my selfbows, I prefer cedar. Seems more forgiving and easy to get lower spined arrows. Hard to find anything below 45# spine with carbons or alum. For my high performance recurves and longbows, I have played with carbons with gold tip wieghts. Hard to get a carbon heavy enough without wieght tubes or brass wieghts.

You can't beat aluminums. I seem always to gravitate back to them.
