The 888x began production in 2010. By this time yoyo playing style had gravitated to demanding bigger wider yoyos . The primary purchaser of an 888 was less experienced and seeking ‘the best’. The design influence was in creating the best yoyo for the person looking for the best… it was responsive, high wall and fun for a lower skilled player.
The 2011 model was less broadly released, for those ‘in the know’ and fulfilled any player demand for performance.
The x was produced for a number of years after this while another ‘players version’ has not.
