I wish I knew someone with a Mezz because I really want to try one. Im sure it wouldnt hurt to buy it and sell it later if it didnt suit my game. Will the Mezz play significantly different than a G series McD?
Both would be VERY different; although, the Mezz more than the OB shaft. Either option is going to give you a more .... *thinking* .... glossy/glass like feel to the shaft. I'm not saying smoother, just a more "polished" feel. (edit: the deflection issue covered above)
With the Mezz you'll also be relearning both hit and feel. The biggest difference I noticed between the McD and Mezz is that the Mezz has a more forward weighted feel than most cues (IMO). edit: The Mezz has a very smooth hit, but not the "wood-to-wood" that you get with the McD.
My choice here (knowing what I know about all 3) is that *
I'd* strongly favor the Mezz .. I don't think you'd ever look back if you did that. (not knocking the McD cues .. just IMO). edit: Note too, that "my" choice doesn't necessarily mean it would be your choice.
