RE: French tuning
No, his article is just on tuning with field points. However, I would think that if you have the bow tuned that well when you use tuned broadheads the impact point should be the same.
Of interesting note. I paper tuned my the WB I had on before and got a good tear. However, when I shot my broadheads I was low and left at 20 yds.
So, I tried French Tuning and found that my rest was indeed off low and left even though with field tips I was dead on.
Therefore, I believe the relationship is the same. If your broadheads are tuned properlyyou will get the same miss as you would with French tuning.
