This is a new product from Mezz, a 11.5mm/W2 size shaft, an expansion of the renowned IGNITE shaft. This item is highly 【rare】 as it is only available through a lottery. The 11.5mm thin specification allows for precise control of the cue ball's contact point. The increased flex balances the cue ball's deflection and curve, and from a player's perspective, the advantage of a thin shaft is that it minimizes 【squirt】. In modern times, more and more top players worldwide are using thin shafts. Recently in Japan, there's growing interest in the very delicate games of 【Chinese 8-Ball】 and 【Golden 9-Ball】, and top players in these Chinese games are leaning towards either customizing their shafts to be tapered or using shafts that are thin to begin with. Once you get used to it, you'll find it hard to go back, as the fit of the closed or open bridge becomes indispensable, and you'll feel like you can't play without a thin shaft!(^^) This time, the 11.5mm expansion from Japan's high-quality shaft 【IGNITE】 is a very welcome development, and its performance is top-notch, as any player knows. By the way, the Wavy 2 joint compatibility also works with the standard Wavy joint, so please rest assured m(__)m I have only opened it at home for photography and weight check, and have not taken it out or test-hit it. I cannot accommodate price negotiations based on "how much I bought it for in the past" as I am not in a hurry to sell. To prevent swapping, please understand that all sales are final (3N) m(__)m
