I personally use these Dava "Grip" picks exclusively and absolutely recommend them! I used to use the Jim Dunlop's until Dave hooked me up with these. They really flex well and somehow do what they say... stiff, medium and thin all in one pick. A simple finger roll change can change your attack and strike quality in an instant, between strums! By the way Dave Storey (Dava) is the guy who invented the original CAM system that Kahler went on to develop into what what we all know today as the "Kahler CAM operated tremolo". When you use Dava Picks you assured of same high standards and Kahler type quality! Keep it in the family...buy Dava. Set of 5.
