'Which strings wouldja . . . . ' is only answered by trying different ones until you find the ones that suit YOU, as it is so very subjective, tone, feel, cost, etc.
I'd only suggest starting in the middle of the road: GHS Boomers or Bassics, D'Addario XL's, the Fender roundwounds. These are bright but don't have quite the bark of stainless, can often be bought the cheapest of most bass sets, and would kind of give you a baseline: After these do I want brighter, more tame, a tigher hex-core feel than roundcores, etc.
The GHS Pressurewounds are good for a lot of guys for 'brighter, but not THAT much' coming from flatwounds.
Best of Luck,
JW
