The Innova Champion Proto Star-Stamp Groove is a Speed 13, wide rim distance driver that is straight. An innovative groove or channel on the underside of the rim allows this driver to be molded in lighter weights than other Innova wide rim high speed drivers. The Groove offers super fast, long, and straight flights. It can be thrown low or high and sidearm or backhand. If the Boss proved to be too overstable for you, get into the Groove.
Champion and Champion I-Dye, weights 165-175 grams . 21.2 cm.
"I rely on the Champion Groove for low ceiling shots. The slight turn it has, at mid flight, gives me the added distance I need before it fades back." - Ken Rollins
"The Groove is a big boy disc with a flight similar to a Boss, but with a little more carry for extra distance. Good forehand disc as well." - Nicholas Duran
