I’ve just started my experiment with graphite. Replaced my Cobra Fly-Z Plus w/ KBS Tour 120’s with Fly-Z Plus with UST Mamiya Recoil 110 F4. Only three rounds in, but so far, so good. I’ve been able to control ball flight as needed and dispersion seems fine. I had gotten fitted this winter and the fitter suggested Nippon Modus 3 105’s in stiff flex and said he felt the shaft would reduce vibration enough to alleviate my tennis elbow. I have not bought in to his opinion on this. If anyone has any input on this, I would love to hear.
