Whatever type of broadheads you decide to use take one or two and shoot your bow with them. Most broadheads fly a little different than practice tips. Also when you start putting broadheads on your arrows spin them, and look a the tip if they wobble switch them to a different arrowuntil you find a head arrow combo that spins true. This really helps cut down your group size. Also read some books by Chuck Adams or the Wensel brothers these guys are serious Bowhunters and you will learn alot from them.
