I see very little mention of these La Bellas here; it seems the Light (760FL) and Super Heavy Jamerson (760M) La Bellas get all the flatwound love. I have had these strings on a Stingray for the last few weeks, and am very impressed. The stiffness is very much like the TI Jazz Flats. And the sound is very much La Bella: lots of lo mid punch. If you're looking for TI Jazz Flats feel and something easy on the hands, but want a more traditional flatwound sound, I recommend the 760FX La Bellas.
