First off with arrows. Carbons dont bend like aluminums, they can be refletched but you have to have a jig, they also need to be cut to fit your bow. Inserts can be glued back in.
Tuning tips: Get your broadheads to shoot the same as your field points. There are lots of books out there with tons of advice(more than i can give you in a little post on the internet, especially at 11 o clock at night, lol) Go to a local pro shop, they will be able to give you lots of advice. Some tuning gets technical, you have to move your nock and get clearance with vanes, etc, etc. Your draw length needs to match your body, otherwise you' ll never get your bow tuned. They can fit you at a pro shop. Or, take a yard stick, put it to the center of your chest between your arms, then touch your fingertips together on the yard stick and where they touch is your draw length. Theres more than that, but i cant type anymore. lol. Tell us how things work out.
