Just read about this in a DD email. Anyone know anything about it?
The XB features a unique flight plate design. The idea was to create a design that among other things was geared towards lighter and faster discs. The original design mindset was to augment Japan Open Class (152g ~ 159.9g) with 'XB' mold characteristics. Innova planned on releasing the design but decided to take a different direction.
Available in Champion and Echo Star plastic. Only 135 Echo Star were made and 374 Champion! Collector Item!
