I've had them about 5 weeks now, did a 4 day trip to Arizona, Sedona, as well as the super steep San Gabriels in Southern California.
While my K18's are very very good on my Bionicon Edison, the Megas are even better with more modulation, incredible stopping power that you can put right on the edge of braking versus skidding in all types of terrain and surfaces. So far, brake pad life seems to be a lot better also for this Clyde, compared to my K18's which are really more XC rated than All Mountain.
So far, I am impressed with how well they work and function. They are a bit expensive, you'll have to decide if they are worth the premium tab, but for me Formula is about total control when you are at the limit. I'd buy them again.
