My experience has been for me that fishtailing was caused by the arrow
hitting the bow. Fletching did nothing to stop it, but only tended to
make recovery happen quicker. Changing the spine, arrow length, FOC
(balance from front to back), or tip weight has been the most
effective ways of getting this cured, in descending order.
In the below example, it sounds like the heavier shafts changed the
FOC just enough that the arrow wasn't flexing enough to get the back
end out of the way as it passed the bow. Reducing spine a bit would
be the solution, but since the arrows were already made the only
remaining remedy would be to add tip weight... which is what was
