I just bought a bass that had the Ernie Ball Cobalt Flats Super Slinky (45, 65, 80, 100), and they sound great. I've been using D'Addario Chromes for years now, and I think I may have found my new string. I'll give a little time before I make my final decision. But, so far I would have to agree that you should at least give them a try.They've only been out for a few months but they're not really unpopular.

Great strings. Everyone should try them.
and what I said was lifted directly from wikipedia. I'm not that smart.
