I designed and machined a new stabilizer for my Z7. This was the 7th model I built and found that this configuration worked the best. It has (3) keycut slots in each pocket to use either (1) Harmonic Stabilizer or (2) Harmonic Dampers. Its is 7.25" overall and with (1) Harmonic Stabilizer in front and (2) Harmonic Dampers in the back pocket is comes in at 7.5 oz. Let me know what you think. Thanks for looking.
