Bill; Mark has an open serial number request for an Epic, so I'm guessing his six string reference is to a bass.
Mark; there is no one clear favorite among the members here. Lots and lots of different brands and types have their fans here. If you want, you can click on Search, in the upper right corner of the page, and run a search of different string brands or types; I would imagine you'll find a lot of past threads with helpful information. Personally, my six string Alembic bass has TI Jazz Rounds on it; but that's just me.
