The Turbo Nocked arrow was 25 grains heavier....that may have had a bit to do with it but not enough to believe that weight was the major factor.
Some spin is always needed in weather to stop float or glide: how much? Verify for the arrow used.
All drift on any weight in weather will depend on the ratio of, the area of exposure & the weight of the object. To evaluate the disparity one would need a wind tunnel with consistent speed.
Trajectories & stability can change by adding weight to the end of an arrow.
One dose not wish to set up a bow near critical points, where small differences will show up on target; such as one foot being slightly lower or the bow grip with minute dissimilarity etc.
These Critical Points & Trajectories should be adjusted (stabilized) before the hunt.
One would always want to verify Trajectories & arrow erratics after adding several grains of weight to one end of the arrow. It may fly to a different spot.
