I've used the Dunlop 3 mm stubby for years now...well, not the same one. They do wear out. Quality control on them is pretty bad...mis-aligned molds often leave a ridge around the edge. I have to sand them down slightly to get a smooth tip. I then use a razor to cut "treads, or "score up," the sides to make them less slippery. Because they don't flex and are made of a hard plastic of some sort, I get a great punch and sharp attack form the pick without a lot of effort. There is nothing dull or scratchy about them...very clean, bold, and punchy. But because they don't flex, they are much more difficult to use, especially when strumming. It took me a while to realize, but I found that my thumb and index finger often allow the pick to sort of wobble when I don't want the sharp attack the pick naturally has. The wobbling makes up for the stiffness of the pick. I'm also constantly changing the angle of the pick, depending on what I'm doing...also to compensate for the stiffness. When my playing is really off and I have a hard time using it, I opt for the next closest feeling pick...a Dunlop 205. It's got a slightly different angle on the nose and crosses the strings easier. But it is definitely more scratchy and doesn't have the bite/attack of the the stubby. Though, the grip (it's flatter) is nicer and rarely slips between my thumb and finger.
