Love the ride. We laugh all the way through it and count on being thrown around on it. It's all part of the fun. We always sit close, two by two, with as much space as we can get beween the 2 sides. It creates alot more spin. That would probably explain why two heavier riders would get maximum velocity. If you sit and watch the riders on it or coming off the ride, they are always laughing and look like they're having a blast.
