I'm thinking of switching from my D'Addario Chromes on my fretless. I love them in general, but I find that the notes on the E string are a little too wooly for me, especially above 5th fret. I'd like to stick with flats or tapes as I love the smoothness, and I want a nice long string life too. Ideally, I'd like something close to a flatwound sound with a bit more precision in the low end, and perhaps a little more bite. Currently I'm considering EB Cobalt flats (unsure about string life and heard stories of them breaking?), and three offerings from La Bella: white tapes, gold white tapes and copper white tapes. Any suggestions or input would be great, thanks!
