I'm in the minority here, because Sunbeams don't have enough mids for me. They sound hollow. They are mellow compared to, say, Rotosound Swing Bass stainless steel strings, but they are still too bright for me. I prefer Fat Beams and Pure Blues, because their mids are more balanced with the highs (to my ears). GHS Round Core Boomers are stiffer than any of these, but they have sweet, soft high end AND strong mids.
