RE: INNERLOCK BH's
I agree that the BH aligning with the fletchings (for a compound shooter) is overkill and not necessary.......unless it gives you added confidence. Shooting traditional, I use a metal spacer (much like the thunderheads utilize) to make sure my BH's are all oriented the same way. I couldn't care less if they align with the fletchings.....but I want (since I'm aware I use the end of my arrow, aiming) them aligned the same way.
If I shot a compound, I'd never think twice about fletch/BH alignment. I'd worry about the only thing that REALLY makes one BH fly better than another.........a well tuned bow to THAT BH/arrow.
