Do longer finger nails make pizz. sound different?

[Richard Prowse]

I've grown my nails slightly because I need to play guitar at work (I teach music to classes of adolescents). The nails are not good for bass guitar playing, but I really like the sound I get with pizz. on the big fiddle. The nails aren't actually brushing the strings but, somehow, they seem to give a bit more attack to the sound. They give a sort of NHOP sound and I like it. Any thoughts?
