One thing I'm going to ask: Are you shooting those helical fletchings out of a drop-away rest. If you are good. If not, I think you might have some problems. The other thingis that not all broadheads are gonna fly like your field points. Sometimes you have to shoot lots of different broadheads to find out what flies well and what doesn't. Not everything is gonna fly well, so check it out, maybe look into some different broadheads.
