Magnus Stingers are wicked broadheads!!!

One of the tricks I do with them, is align the main blade vertical with the bow string, by using one of the spare O-rings from a leftover pack of Thunderheads.
That's a good point, Butch. I had forgotten that I did that as well, but w/ my fall away rest all I had to do was turn the nocks.....The cock vane's location is of no consequence. Try that once, turn the blades parallel to the string and see if that helps...
