I put nylon LaBellas on my no-name jazz copy a couple of weeks ago, and had to take them off, because they take all the snarl out of it. I like the lack of finger noise, but there seems little point if it doesn't make a noise I like. Flats on a P-type, yes I think I need to try some half-rounds, see i I can keep the snarl but reduce the finger noise.
