Matt Moulson of Buffalo Sabres has been working directly with STX to perfect the Surgeon 500 giving feedback to a quicker release through the Power Flex Profile™ which is a constant flex that maximizes energy transfer. With 12K Carbon Construction throughout the shaft and blade of this stick provides an elite level of power. Increased Stiffness in the blade construction and an ultra high balance point amplifies the feel and play-ability of the stick. The STX Surgeon 500 is a great stick for those at a higher level that demand perfection and a stick that gets the job done.
