Those who tune to a bullet hole through paper at 6 or 9' produce a "knuckleball effect" on the arrow and it will take longer for it to paradox correctly, thus IMHO is not the best choice for supreme
accuracy at all distances. What top shooters and techs have found over the years is that an 11:00 tail-high left tear approx 1/4"-1/2" (right handed shooter with release) at 6-9' will produce a faster and more repeatable paradox on the arrow coming out of the bow, thus the arrow is more accurate. My findings have coincided with this theory,
Personally, I have never gotten great broadhead flight with a tear anywhere near that. When shooting broadheads. There is only one rest position for that arrow that will not plane with broadhead attached. This can only be found in the field when doing a walk-back with broadheads. I usually shoot through paper when I'm done broadhead tuning - just to see what the tear is - usually it's a near bullet hole with a field tip attached.
There has never been only one thing that gave me great broadhead flight. It's a combination of things that add up to really good flight in all conditions. The things that I've found that are critical include - high FOC, helical fletching, spined tuned arrows and walk-back tuning with broadheads attached. For me, paper tuning has never entered the equation.
