AD Trads. Pick your poison for an overall weight range by using either Lites, Regulars, or Hammer Heads. Choose your desired components and start with a full length shaft. I like to use a strip of plastic cut from a sandwich bag about the width of your fingernail and long enough to go down the length of the insert and back up the opposite side. Press in the insert and it should hold well for flight testing into medium to light density foam. To remove the insert, clamp the broadhead (or point) into a vice and pull it straight out. Keep adjusting for length until you hit the sweet spot where you have quiet flight and the arrow recovers and flies straight downrange to your target. I normally do this with a fletched shaft and my hunting broadhead shooting from 30 to 50yards. Once my broadhead is adjusted to fly true at 50yards, all my small game and stumping heads also fly true. Very simple and very effective.
Best,
