mo, I started to use carbons this year, I was using 2315 30inch and with my bow 1983 jennings forked lighting 70# it shot aluminum at 198fps. while I was at the local pro shop they gave me a gold tip to shoot and it shot 225, I was going to get them but instead I got PSE`S carbon force 300 29inch and these shoot 229fps, I haven`t shoot a deer with them but i might get 1 tonight after work, I will not go back to alum because they shoot so much faster and flater and my groups are so much closer
