Etry with square-corners, while the intermediate, junior and youth uses a contoured geometry with rounded corners for better fit and feel for smaller hands. The rbz™ stage 2 comes with the grip finish plus is also available in non-grip for the senior models only. There's really no visible taper to the rbz™ stage 2 because of the constant flex profile, just a nice transition of where the blade and shaft meet. The blade is where the most significant advancements occur on this stick. If you thought the puck came off your rbz™ with high velocity, you'll probably freak out at how much faster it will be with the rbz™ stage 2. What makes it freakishly fast? speedblade 2 has freak channels. Instead of using foam in the core, finely tuned channels circulate through the blade in such a way that the coefficient of restitution or c.O.R. Is increased by 20% in comparison to the already fast speed channels design of the rbz™. Basically, this is a trampoline effect of the amount of energy return at the point of impact which results in a shot with increased velocity. These are some of the same principles that power the taylormade® rocketballz™, which is why you'll find the "powered by taylormade®" graphic proudly displayed on the stick. Original box
