I kinda take a pinch of salt with the "world record" bit. As you say, Eddie pulled 500. Both used straps and hitched, strongman style. Both were in a strongman comp. It might be that the "world record" was like the slogan for Lemon and Paeroa: "World Famous In New Zealand". Or more likely, since it was Rogue sponsored and held in the US, nothing else matters out there in the real world.
