Simply put, the Shell Celluloid picks in heavy gauge give me the precise attack I need for heavy rhythms and solos (due to it's gauge and sharp tip).

That being said, be careful when experiencing with the different color patterns, because while they're all made of Celluloid, likely due to the individual color mixtures used, they literally affect the tone and attack some when using a different color schemed pick of the same gauge even. The tips are sometimes different as well; some are sharp tipped (Shell heavy) and some are comparitively more round (Black heavy)in my experience. Generally you needn't worry, but if you've been playing long enough, your senses are more keen on picking up these subtlties - enough to affect your sense of feel.

Fantastic buy if you want a more vintage tone and warmth in a standard sized pick. I like it not because of those things, but because it just feels and plays perfectly for me.

Dunlop is always great, and these picks are no exception. I bought a pack of the heavys from a local guitar shop and got screwed on the price. buy these. it doesn't get any better.

These picks are great. I've used some of the "rough" picks in the past, but I like how these slick ones "stick" to my fingers. I've used the Fender ones too, as well as the Jim Dunlop "gel" picks, and it could be in my head, but these seem a little stickier and a little more durable. They also hold their shape better, they don't get bent out of shape. I like the confetti colored ones because I think they look the best, and they are easy to find when you drop them (unless you have some really crazy carpet.) I only put a 4.5 on value because, like all guitar picks, they're a bit pricey for something made out of plastic, and there is no option to buy a large pack of these either.
