Well, I got mine in yesterday. Played around a lot with pickup height and pulled them out. They are impressively quiet and have a true single-coil tone. The problem for me is they don't have enough lower mids and the highs have a brash quality. Not a pickup that works well with overdrive for ME.
Esoteric arguments to the contrary, microcoils really do have a crazy amount of magnet pull coming off the top of the polepiece screws.
