Wentzle Ruml lV was a member of the legendary Zephyr skateboard team, he was never the most prominent member of the team, but is credited with being one of the pioneers of pool skateboarding. Stacy Peralta credits Ruml with pioneering the 360 slide and Tony Alva says he was the first to pull off a 180 lip slide into a 360 roundhouse back into a 180. As the team began to dissipate, Ruml moved to Hawaii to skate and surf with Jay Adams.
