I rotate between these for the most part. The Honey-Picks Bumblebee V2 shape on the left is made of Kirinite - a hardened acrylic. It's bright, and great for rock, power pop, fusion, etc. The Pickboy Modrez in the middle is made of resin and is warmer/darker than the other two picks. It's good for jazz and ballads, stuff like that. The Gravity Gold series pick on the right is made of a kind of space age thermoplastic that is impervious to wear. I've had some and played them exclusively for a good 5 or 6 years, and they show no visible wear. They have almost a neutral tone and brightness - sounds good for for just about everything. I just wish they came a half millimeter thicker, because they feel thin to me (my favored thickness for electric guitar is 3mm). Those are mine, let's see or hear about yours.
