This Two Foil Robert Burridge Gorilla stamp desinged by Gorilla Disc Golf, features Gorilla foil & then a seperate foil for the RB, Lone Star Disc & Gorilla Disc Golf logos. A portion of the sales goes to support Robert Burridge. The Tumbleweed is a very understable 10-speed driver. Even if you’re a player with a slow arm-speed, you’ll be able to handle the Tumbleweed like a champ. Or, if you have the power, use this disc as a super-flippy roller or tailwind driver. Lone Star Bravo plastic is more pliable plastic than the Bravo.
