It all depends on what you are doing. For me, I bash my rusty, but I dont really do much insanse stuff and I dont take that many jumps that could damage a part. The only time I ever have problems with breaking parts is when I crash into something head-on which is quite rarely. Therefore I think carbon fiber would be good for me. But for the guy whos out there jumping cars and stuff, that cabon fiber isn't going to last a day. It all depends on the application.
