First of all, have you got your field tip arrows flying perfectly? Do you shoot good groups with them? I suspect you have a tuning problem. Next, Are your broadheads mounted so that they spin perfectly true and straight? I would check arrow spine, point mounting, and fletching what is your set up for fletching? I like a 5 or 5.5" feather mounted helical. There are a lot of variables with broadhead flight, Those are only a few. Those heads you mentioned should be no problem to get to shoot well. The head is the first thing people look at when it should be fine if it's on straight.
