Putting them on all my basses - they last a good long time with the coating, sound GREAT, and after playing these, anything else (stainless or nickel) feels like they have rosin on them.

I like slinkys for a fatter sound or hi-beams for a growlier one on a MM. I never got a chance to try Fender 7150s on one, but that'd be a good choice for an even fatter, deeper sound than the slinkys.
