Go to www.eastonarchery.com and pick the Legacy arrow chart (upper left hand of screen). This will give you a chart for choosing the correct spined arrow for your bow. These will be for aluminum arrows.
There are many great broadheads, like Magnus, wensel woodsman, ziwicky, phanthom, etc. Shoot whatever groups best from your bow. Might take a few tries but that's part of the fun. Others on this forum will be able to help better with selecting wood arrows. Good luck!
