I use Elites Stadium Series Standard V's (130 105 85 65 45) on my Warwick Corvette Standard V. They are roundwound stainless steel strings. They cost about £15. I use Elites on all my basses.
I found a review on the web which described them as "Solid, warm fundamental -Ringing harmonics, but not annoying -Bright, deep slap sound -Warm fingerstyle sound, bites back when you dig in". I'd agree with that description.
They may be hard to find outside the UK, but are well worth checking out.
