I have tried to grow my nails off and on for the past seven years. Finally, when they were just starting to grow out to a decent length, and I was getting a decent sound, my M finger got this harmless growth, a ganglion cyst, which started pressing on the nail bed and causing that nail to grow out all ripply. I tried the Alaska picks, and other things, but they just don't feel comfortable. And, while the cyst has decreased markedly, the nail seems to still be growing in that weird pattern. So, even though I'm trying again to grow them, I think I may, too, just give up the ghost and use flesh. Many have mentioned Rob MacKillop, who gets a wonderful warm sound, very expressive, with just flesh. It's hard to imagine people have abused him over such. He gets such a nice sound. And, since I don't need to fill a concert hall, just my living room, having nails is a lot less important, and it makes the rest of life a bit less awkward as I don't have to fear breaking or chipping them.
