As someone previously stated, string choice is a personal thing, however, I used to use Roto-sounds-exclusivly-until this guy Dave Donley GAVE me a set of Curt Mangan nickel wounds to try.
Now, granted, he owns the music store here, so I too at first thought he was just trying to get me to buy them...if so, it worked 'cause these are the strings I use on all three of my basses now!
They are bright, but not twangy, warm, but not dull and they last three times longer than the Rotos-and they are longer-string thru body not a problem even on my jazz 24 G string.
Food for thought.
