RE: aluminum
I started shooting carbons with the last bow I bought. The pro shop talked me into it. Said I was the last of a dying breed. Almost all of their sales are carbon and judging by what was behind the counter waiting to be picked up he was right. They do seem to shoot a lot flatter and I have had no problem with them. I actually do like them. That being said I had no problem with my old 2315s and still shoot them in my old finger bow and intend to continue to do so.
