I like the look of them, and they have a cool visual effect when in motion, but they don't compare ride-wise to Franks. I know it's not scientific, but after I install and inflate a tire, I habitually bounce the wheel: the Franks are like those old blue wham-o super balls, everything else (so far) feels kinda dead. I'm guessing this is due to a combination of weight and a superior compound. I also noticed the Circuits checked very quickly, where Franks haven't.
