Besides the Labella LTF's, What are some other choices for a good Low Tension Flat wound set? Preferably 45-105 or ? maybe a little thicker guage; right now I have a set of Fender flats on one of my Jazzes (45-105), and although they're not super stiff, I'd like to find some Flats with a little more give/flexibility to them. What other choices are out there? Thanks.
