What spine arrow do I need?

What does GPI mean on an arrow?

Grains per inch

What arrows should I use for 70lb bow?

Are carbon fiber arrows better than aluminum?

Carbon arrows are way better than aluminum due to their durability, strength, and weight. Aluminum arrows are cheaper than carbon, yet they are not nearly as resilient or effective. Therefore, when choosing arrows for archery, carbon is the best option.

Which is better carbon or fiberglass arrows?
