I'm really glad that we have one of the best of the Schwarzkopf shuttles right here in Southern California---Montezooma's Revenge!
Personally, I've only been on this one and what was Tidal Wave at PGA. Without a doubt, the flywheel model, like MR, is far superior to the weight drop ones like Tidal Wave.
I hope Knott's continues to operate Montezooma's Revenge as long as they can. Even 28 years after it opened, it's still one of the best rides at Knott's.
