I had the threads on a Mezz EX Pro shaft cut and modified to a 10-pitch thread for a Musashi cue. There's a crack in the ferrule. The tip has been replaced. Asking 3n. "The EX Pro shaft, designed as an original shaft for Exceed Cue, enhances power by using a two-stage carbon fiber core, approximately 470mm long from the joint end, to equalize the shaft's flex. Furthermore, the new structure at the tip of the shaft (EX Front End Technology) provides a natural hit feel similar to a normal shaft, while also achieving lower deflection. Equipped with a ZAN Plus2 M tip as standard, the original EX Pro taper further improves cue ball control."
