It's not as important as people make it sound. If they're not aligned but fly good that's fine.
I can say with certainty that any straight and true spinning broadhead will fly like a field tip out of a well tuned bow and arrow set up regardless of blade orientation.
You better get those arrows fixed up fast smossy girl! Before they realize that they are not to fly straight without being lined up. Hopefully nobody tells my arrows either.
can someone come tell my arrows to fly straight? please and thank you.

Can you cut the vanes off of a field tip arrow and shoot a group at 15-20 yards with 3 field tips and the field tip with vames cut off? Then post a pic. If the bare shaft groups with fletched arrows you should be good. If not some tuning is needed.I have absolutely improved grouping on broadheads by aligning the blades with the fletches. there is no reason at all it would affect flight in any way as long as the broadhead spins straight. How would you line up a 2 or 4 blade head?

Simple as that Bullblaster.Otherwise what do guys do that shoot 2 or 4 blade broadheads? Fletch with 2 or 4 vanes?I've shot a couple dozen different broadheads out to 50yds in my yard numerous times. They don't line up with anything cuz I just screw them in tight and shoot them. Once the bow is tuned, they will shoot well or the difference will be so small that a slight sight adjustment will take care of it. That said, broadhead orientation WILL make a difference out of an out of tune bow. IE: Rest too low. FP hits bull. 3 & 4 blade roadhead hits low. 2 blade broadhead hits low when installed horizontally. When 2 blade installed vertically it hits same as FP. Why? Because immediately off the bow the horizontal 2 blade and multi blade heads catch air because of the rest being too low causing the broadhead arrow to plane down slightly before the vanes can counter act and stabilize the flight. Too late. Already a couple inches low.I've even got a bunch of old, large broadheads from the 60's and 70's up to over 200grs that fly just fine out of my tuned bow. When out of tune, these huge heads fly horribly because they catch a lot more air than today's small heads.Areodynamically speaking, if the blades actually created that much air disturbance that it effected the air flow to the vanes, the vanes couldn't do their job of steering and stabilizing the arrow. From the OP's original post, it sounds like you might need to fine tune your rest. See if this link helps you out.http://www.archerytalk.com/vb/showthread.php?t=1606741
It works for me. That's good enough.
