See I don't know; but what I found is funny is that Players does not even supply their own tips on their shafts... they come with Kamui tips.
Not with this ones...but if u looking for an tip with great quality and the feel of the old mooris, try an G2 tip....
I have been playing with my new tip for a month and a half and really like it. I have it cut down to three layers with a little more than a nickel radius. Shaft is 12.7 mm. I ordered a soft tip. It feels almost like a medium now. It is not showing any sign of glazing. Does not feel mushy, has a firm but kind of soft hit. Everyone that I have let try my cue has liked it. The only thing I don't like about the tip is that it does not make a sound.
