Team Hyper Viper (THV for short) was a two-man sponsor team consisting of Dave "Dazzling Dave" Schulte and Jon Gates, formed by Bandai to promote the Henrys Hyper Viper yo-yo and the offstring playing style in Japan. While they went with other teams, such as Team High Performance, to demonstrate most yo-yo tricks of the time, Schulte and Gates had also demonstrated offstring play using the Hyper Viper.
