Well... Over the years I've moved from hex core to round core.Then a Series came into my life with Alembic strings, which are hex core. As much as I liked the sound, my fingers weren't too happy, so I went to DR HiBeams. Next, TI Jazz Rounds. And finally TI Jazz Flats, which are just starting to settle in so they're still fairly bright - but no amount of CVQ boost will make them roundwound bright - though I should say the wood recipe on my bass doesn't particularly favour brightness. What I remember from EB strings on my Spoiler is mostly that they came off after not much playing time - dull roundwounds, not for me. But whatever your string choice, you need to look at the complete package, from the strings you play to the speakers that make the big noises, it all adds up (or subtracts).
