Ryan, What if that left kick was being caused by nocks that were/are too tight?
What if that left kick was being caused by some quirk in your form?
What if that left kick was being caused by the arrow being too stiff to start with and the tail end is hitting the bow causing it to give a weak indication?
Bottom line is many things can cause an arrow to kick in any direction that have nothing to do with arrow spine and can never be fixed with tuning techniques. Use the planning method instead of the "kick" method. Another tip, never ever cut a shaft until you verify with point weight first otherwise if the problem is over stiff to start with, you'll not correct the problem and ruined an arrow in the process.....O.L.
