RE: Broadheads don't fly right
Do the arrow spin test fine???? If they do, I'm thinking you may be getting a little fletching contact somewhere. Sure, you can go to a mechanical head, but is that fixing the problem of the untuned bow??? Also, you're losing energy if that arrow is spiraling like that, which is certainly not going to help you any. ST's have flown GREAT for me, as they have from quite a few others, you may look at a different BH for your solution also.
