CAUTION: High powered bows create a great amount of vibration.  This may loosen Verifiers, Clarifiers and Apertures over time.  Tighten your Apertures before each use.  If you hear a buzzing sound, this indicates a loose Aperture.  You may use a drop of Vibra-Tite VC 3 (#VC3), Teflon tape, bow wax, or any other non-permanent binding agent on the threads.
