dwditty sent me a note about a guitar store in New Haven, CT, USA which sells picks called "Cool Picks." I went to this very upscale guitar store and bought a few picks at 50 cents each, and they are great. They have tiny bumps dotting the hold area consisting of some sort of plastic or rubberized coating which makes them easy to grip. And the pick itself is very nice looking and easy to spot, a kind of white marbled plastic.
The store, by the way had all kinds of unusual things like Alembic and DeAngelica guitars, stick basses, Granada banjos, Cool Picks, but nary a Martin!! G Guitars
