Depending on what kind of cue you have you might be able to use the Mezz wavy pin shaft if you dont find a radial. I had a Predator with a radial pin and my Mezz wavy shaft fit right on it. Similar to the way Joss and Schon shafts will interchange on one but not the other. The wavy shaft fit my radial pin cues but the radial pin shafts will for sure not fit the wavy pin butt.
