P90 fans: Have you found any other kind of pickup as good as a P90? At the risk of being repetitive, I'm about to put a Mean90 in the neck position of my second build, after already having one in my first build. But they are perfect for me. Humbuckers are completely missing some sparkle, and regular single coils have, well, just a tad too much of it (at the expense of some low end). But I'm oversimplifying here of course and wondering what I'm overlooking.
