I used Sunbeams for a long time, then switched to Pure Blues for a bit more oomph in the lower mids, or Fat Beams when I want stainless steel punch. I'm totally addicted to the flex of roundcore roundwounds, which all of these three have in common. And yes, a bass may tell you what it wants, but the styles of music you're playing will also place demands. The Fat Beams were a recent purchase, in looking for a bit more brightness and cut in a rock/alternative band - and I got exactly what I was looking for. My usual bag has been jazz/latin/folklorical, and likely will continue preferring nickel rounds in that world.
