Wow!  I just received this cue after a trade with Troy.  It's awesome looking and feeling.  Although I haven't hit a ball with it yet, I just wanted to report that the shaft is much "meatier" than expected, which was my main concern.  The very tip is 12.48mm, below the ferrule it gets thinner for about 2-3 inches 12.24mm probably due to years of sanding, but 8" from the tip it is over 13mm.  I'm confident it hits like a monster as advertised.  I can't wait.
I will say that Troy was the most professional person I have personally done business with on AZB forum.  Including shipping labels, invoice, communication, packing, etc.  And I have had a lot of successful transactions in this forum, for which I'm grateful.  But if you ever get a chance to work with Troy, I would do it!
Thank you Troy, 
Dave
