Hey, I want 2 cents in this! Here is my findings. And I have a garage full of all three materials.
Metal; If you want to put some arrows together fast and whack targets. Good for coyote hunting since they will bite your arrows. Pretty light so I would have to add weight. I like them for FITA shooting.
Carbon: UGH! Took me much time to find the right spine, weight, cutting for spine. I really like the Alaskan Grizzly shafts. But $$$.
WOOD: Now that is where I alway go back to. If I get shafts from makers like Great Basin(Kye)they are perfect! Straight, exact weight and once sealed they stay that way. I have shafts I still shoot from Kustom King from 1984-5. Smooth,quiet and just fly great.
