If you've never heard Robert Conti play, Google him and prepare to be amazed. He bills himself as a 'street player' and his teaching method is summed up as follows: you learn to play jazz by playing jazz, not scales and modes. This is the pick he uses. It's the thinnest pick I've ever held and after years of using a heavy pick (mainly Jazz IIIs or something of that size and thickness), this took a little getting used to but the danged thing works like a charm. Rather than displace a string----which is what a heavy pick does when it makes contact with a string---this .38 mm pick 'snaps' over it.
