First off,don't take this personal.I am only trying to offer possible solutions to your problem.That being said,Form problems are more likely to show up with a broadhead than a fieldpoint.The wings on the broadhead(blades)will be more likely to steer an arrow off course on a bad shot.Especially with straight or slight offset fletching.What kind of bow are you shooting?A low brace height bow aggrivates this problem.I have also seen people have to tune their drop away rests by shortening or lenghtening the cord attached to the cable slide.If the rest is dropping to soon you may not be getting enough guidance to the arrow before the rest drops.This also would make form problems more accute.Weigh all of your finished arrows and broadheads.Find out how close they are.If there are enough differences in weight that could aggrivate the problem.Perhaps your drop away rest is not falling consistently.The cheapest possible solution maybe to try a different broadhead and see if the same problems still exist.I allways had good flight out of thunderheads.You might try those.If the problem still persists,either you have a mechanical problem that is intermittent(I would suspect the rest)or every now and then you are making a bad shot.I do it sometimes myself.Collapsing a little or torquing the bow at the shot.Good luck,these kind of things can drive you crazy.
