Building on the success of the popular Diamana D-Series, Mitubishi Rayon unveiled the third generation of the company's "White Board" shaft, called the W-Series, a low launch, low spin model that provides improved control and a tighter shot dispersion.
Along with its predecessor, the Diamana 'ahina, the White Board line — known for its white background behind the Diamana logo — has captured more than 100 TOUR wins globally since its inception.
Tiger Woods is the most notable name playing White Board at the moment, after he switched earlier this year from Graphite Design's Tour AD DI-7 X to a Diamana D-Series 73x (also known as Diamana White Board) at THE PLAYERS Championship.
The shaft Woods is using — it debuted in 2007 and was first used by the 14-time major winner in 2009 — has received some noticeable improvements over the years. Compared to the 'ahina, the new W-Series has a modified and slightly stiffer butt section that's reinforced using Dialead, a pitch-based carbon fiber, in the hoop layers to prevent shaft "ovaling" and improve stability at impact.
The W-Series also features a softer tip section that's very similar to the original D-Series shaft. While the shaft is still considered low spin, low launch, the trajectory should be slightly higher than 'ahina.
