Got these on a whim almost a year ago and finally threw them on. Not really a MM fan, I like his sounds, and these do sound a lot more like his sounds than the dead nickels that came off. I didnt realize that they were stainless when I got them. Golly, they have chewn up my fingers something fierce! Worse than Rotos. Anyone had these able to say if they break in as, eh, extremely as Roto 66s?
