I just switched to La Bella string for a 4, and I play Southern Rock, Country, and Blues!
My instructor plays these same strings but on a 6, playing Jazz so I guess I would come down to preference!
i second the TI's...they have a really small guage outer wrap, so they're really comfortable...expensive, though...steve barr, the dude here at talkbass, also runs the dudepit, has the best prices on TI strings. dean markley sr2000's are great (steel taper wound strings) and i also like d'addario slowounds (nickel). DR lo-riders sound really great, too....and i think they are now available in either steel or nickel.
