After years of Playing Ken Smith and D'Addarrio Nickel Strings, I switched to DR SS a few years back. I really love the sound and the feel does not bother me a bit. I think I have calouses that are a few feet thick...lol.
Well, I got a Ken Smith Bass yesterday(

).....and I was shocked at how much I did not like the Nickel Smith Strings that were on the bass, even after loving Smith nickel strings for years. It is simply the brightness and the grip that I miss from the nickel. i would rather tame a zingy string than try to coax life from s dull sounding string I guess.
