Somebody told me the brass Alaska picks can be adjusted to your finger.
I once read that John Renbourn used ping-pong balls. He would cut them into strips, paste them on his fingernails and then trimmed them. I haven't tried either the Alaska picks or the ping-pong balls, so I just throw it out for what it is worth. I plan to buy some Alaska picks for the next time a nail breaks. I was tending towards the brass ones; but in light Micks idea of trimming them, I might go for plastic ones.
