Well if any of you have a problem with that, try making every thing straight with eachother.
It's been proven time and agian that vane to broadhead alignment doesn't change arrow flight. Obviosly, your broadhead has 4 blades so they can't "align" with the fletchings. You have some other issue going on that nothing to do with vane to broadhead alignment. Maybe fletch contact with the bow or arrow rest.
