I have a few questions and recommendations. Are you new at this archery game? If so then I would not even give a thought to what broadheads would be the best for you. You're likely quite a ways from being ready to hunt.

You know how to shoot and tune a bow? This is things you need to learn before thinking about what broadheads are the best, because the best won't do you any good if you can't tune the equipment to get them to fly well. Just learn more about shooting form, getting the draw length to fit you to a tee. Learn how to tune your equipment and basically how it works. This all takes time. During that time you'll learn a lot and if you get active with a club you'll pick up a lot of useful information and hints along the way.

Maybe some time next summer you can think about broadheads.
