As we all know it is hard to get the proper alignment for broadheads with a carbon arrow. I did some thinking and here is the best way. If you have a new arrow, ( unfletced ) put the broadhead on first, set it on a flat suface, then turn the knock to the proper alignment , now fletch the arrow. If you you are using arrows you already have then take off the fletchings put the broadhead on turn the knock and refletch.
