The Musashi line of cues from Adam, is what Adam calls it's custom cue line. I've played with a few, and know a couple of pro players in Japan that endorse them. Custom cue? Well, kinda sorta. Generally Adam cues are production line type cues. The have several well trained craftsmen that run the machines that pump out the same designs over and over again. Then there are their supervisors or master cue makers, and these are the guys that make the Musashi line of cues. I must say however, as with most Japanese products, the attention to detail and higher levels of tolerance makes any Japanese made cue (Adam, Mezz) a well made piece of wood. The problem is, all Japanese products are priced according to the Japanese economy, and will always have a hard time selling anywhere outside of Japan.
Very well made cue, but for the money, you can go with other options that will not only get you a great cue, but a little more name to go with it.
