I get that everyone here hates the 9 Club and thinks Roger is a kook, and that's fine, I mostly agree, but everything he said about the wheels mirrors my own experience as a paying customer. They absolutely blow the 97a Spitfires out of the water, they reduce the fatigue on my aging back, they slide beautifully.
They are not my great wheel for brand new, glass-smooth skatepark cement, but for every other surface where I've used them, they're a huge improvement.
