Everyone sounds right on and assuming your form is right, sounds a little week. However, fleching may cure that. I have started bareshafting and then take my bare shafted arrow and put fletching on and test with field point and then my broadhead combo that I know will always hit dead on with a properly spined arrow. If the arrow will hit dead on with all three, its good for me. Assuming your are using carbons or aluminums, you can duplicate the arrow spine combination to get the same spine (and retest).
