Aligning a 3 blade broadhead to the vanes of an arrow is an old wives tale and has been debated, debunked, and myth busted.

I use Magnus Stingers and all I do is align the main blade vertical with the bow string. How do I do this? I use the spare leftover rubber "O" ring from a pack of Thunderheads, put it on the ferrule of the Stinger. It allows the broadhead to get tightned and allows a little play either way (snug), so I can align the main blade vertical.
