I have used Jazz III picks since I started playing guitar. I loved how the smaller picks game me more control than a larger one. Lately I have changed my ways to larger picks, but that is a story for another time.
If you enjoy the Jazz III picks, but want more grip, then these might be what you are looking for. However, for my taste they actually had too much grip!
While playing I often find myself changing the position of the pick between my fingers, but with these I had to start out with the perfect position because after I started playing I could not move it without a total reset of my grip.
If you are curious of these picks, I reccomend you try them out before buying too many, but if you like them, they are solid and durable picks as Dunlop always carry!
