D'Addario Plain Steel Double Ball End, .010, SPL010star rating 5mooncaineDecember 29, 2009These are my favorite strings for over 10 years. Long-lasting, great tone. The only thing I'd change is the design of the package. It's hard for me to tell which strings go for Steinbergers, and I've accidentally bought a few packs of strings that weren't double-ball. They are awesome strings, though. Kudos to JustStrings for selling individuals of the high strings. C'mon and sell low strings, too!
