Yes they look very cool but don't perform or feel very well. Originally they were adjustable part drivers used for fitting and they kept that concept alive which I like but when I hit one and this isn't only my opinion it feels like it's more than 1 piece or there's something not sealed which could mean lost energy where as a Monocoque head or a driver that is made completely sealed has a more pure vibration/feel/sound to it if that makes sense. It all looks really good but even in Japan it's not considered a top performer.

Good to know!
