KC Pro plastic

Made by Innova

KC Pro, just like regular Pro, has varied a lot over the years. However, KC Pro has stabilized in recent years to mean "hard Pro." KC Pro was the first premium plastic released by Innova, and it was originally a harder version of DX. KC discs are obviously Ken Climo signature discs, so whenever he would win a new world title, Innova would update the stamp for the champ. In the early 2000s, KC Pro changed a lot. Some KC Pro was made in Special Edition plastic. Examples of this include the first year of 10x Plastic and all 10x Rocs. 10x 11x Aviars were actually made to be slightly gummier on purpose as well. Later 10x and early 11x KC plastic was made in a proto version of Champion Edition. (Source: u/IsaacSam98)
