When I opened the box I was sceptical, these picks looked just like my jazz 3 picks after a week or 3 of playing. After a little while you start to hear that these picks are more than just played in J3's, I'm not sure if it's the material used or the "hand sculpted edge". but these pics can be very subtle. They're a nice mix of the jazztone pick's string-release and the featherweight no-mass to the table jazz 3's.
They sit right in between these 2 picks as a nice hybrid of them, Jazz 3's have more snap to the attack due to the edge, and the jazztones just have more weight to them,
All in definitely a pick you should try if you're into picking dynamics or just really subtle pick-attack.
