I use all three common arrow types for sure and I enjoy them all for various reasons. I do still shoot a lot of aluminums for general backyard shooting because I can shoot a couple dozen of them at a time before I go get arrows and they are durable enough to withstand that (more than woods are). This is mostly selfbow shooting. When I shoot my higher performance bows, I use carbons. There is just a certain feeling that aluminums have with a lot of bows, especially older bows. They feel a lot more like a wood arrow out of an older bow or a selfbow and they last forever. I have a few that I still shoot that I bought new in the late 80s or early 90s.....a 2213 from 1990 is still a 2213 now, and thats an advantage too. I'd love to shoot woods all the time, but to be honest, I'd just go through them too fast and then I send up with mismatched sets. I suppose the way around that is to order the shafts in 100s rather than dozens. I suppose the final answer is simply that I like how they feel out of certain bows.
