These are the best guitar picks you'll find, don't bother looking elsewhere. At first, you'll find them difficult to use because of their size, but once you get used to them, there's no better. They are a little slippery, but I believe there are "max grip" versions of these picks that will solve that. The pointed tip is the most important aspect of this pick. As for acoustic guitar, you don't want these. Get a soft nylon pick for acoustic, you won't be able to strum with these very easily, they're stiff. Highly recommended to everyone.
