Been shooting them for quite some time. Make sure you spin-test your fixed broadheads on the shafts. If the broadheads wobble on the shaft - even a little, save those arrows for practice or mechanical broadhead use. You can heat the insert with a broadhead installed and turn them ever so slightly and re-spin them to see if they will achieve a true spin with no wobble. IME the ones that spin absolutely true with fixed BH's will group right with your field points - assuming the spine and bow is tuned properly.
