Hi I need to look at the j/ps , forgot they needed touching up . Yes the diametor is smaller, don't remember exactly what right now, but smaller. When I gotr it back , felt a little big to me also. I like it know, tried it out , a little last night, like it smaller. The preditor shaft , with , Ivory ferrel, and Wizard M tip. Hits great. It measures just under 13.mm . easy to turn down, hard to grow back bigger . Still playing with the finish, had to refinish whole cue . Couple little spots not happy about, hope to get them by tommarro, going back to work Weds. Thanks Jim
