The Spinosaurus is a "12 speed" driver, meaning it needs a little more armspeed than other Dino Discs to use its full potential. This disc is a great step up for a kid or a beginner who is "turning over" their other Dino Discs (when they throw hard the disc ends up rolling or veering off way to the right for right handed players). This is also a great disc for kids to grow into or use as a first forehand disc.
