is your bow centershot? if not, knock an arrow and look at your bow from the front. which way is your arrow pointed, in towards the riser or out away from it. if its in towards the riser try putting a small piece of a toothpick behind your strikeplate (put it on parallel with your arrow so that the shaft rests against it). If it points out and away from the riser then you can address with smaller diameter shafts or adjusting the spine.
shoot some bare shafts from 10' and see where your nock ends up in the target (left or right). that should tell you whether your under or over spined.
