it sounds as if your arrows are underspined according to the description of the tear you are getting.
back the draw weight down to about 68 LB and see what happens
are you using a heavy point like possibly 125 GR?
if so you can go down to 75 Grain, doing this will keep the arrow from flexing as much.

or it could be as nub stated,you may be getting fletch contact or if you have a dual cam bow it could be a timing issue.

when I tune a bow I get a perfectly round hole with 3 fletch tears
