The helical of the fletching and the length of each fletching as it contacts the WB can not be consistent shot to shot.
With the correct spined arrows and well tuned bow , it most certainly can and is consistant from shot to shot. That is the brilliance of the Whisker Biscuit! All three fletches will contact the biscuit the same way on every shot.
Correct me if I'm wrong, but isnt a correctly spined arrow suppose to bend as it leaves the bow ?
