There are several top quality b-head designs to choose from today. Don't scimp,.... this is truly one item you should NEVER get cheap on!!! My favorite, and by far the most devastating I've seen, is the GKF Demon aka Steelhead. These heads fly like darts.... exactly with your field points and hit like a ton of bricks!!! The solid steel ferrule will hold together no matter what you run into and the head penetrates like no other!!! Of the 15 whitetails (up to or exceeding 300#) I took with this head NOT A ONE has taken more than 60 yards on me!!! Those are results you can count on!!!
