I don't use fingerpicks at all because I just don't like the feel of them. I used to suffer from nail wear and breakage and tried various things. But what works best for me is keeping my picking nails a little shorter than before...in fact so they just "peek" a little above the finger pad. This way I get a satisfactory combination of finger pad and fingernail sound but with very little nail damage or wear...even when picking blues quite heavily on my resonator guitar.

Peace
