TI Jazz Flats versus La Bella Deep Talkers: which is better?? I am going to buy new strings today. These are my two choices. Here is what i look for in a bass string: 1. Flatwounds w/ ultra smooth surface (no roundwounds for me thanks!) 2.Lots of depth 3. Low cost Which of these strings is smoother? Which is more cost effective? Why do you prefer one over the other? Thanks!
