It isn't that hard to "tune" a fixed head.
Make sure your bow is properly paper tuned
I buy a G5 squaring tool and square off the insert (not needed but helps)
After that buy your self a little $30 arrow spinner and say you have a dozen arrows spin all of them and find the straightest arrows. Then spin your broadheads out of all the fixed heads I have used I have never had a single problem tuning a fixed head.
Remember if it takes energy to open a broadhead it will take energy away from the penetration two holes are better than one.
