I use Jim Dunlop 1mm Nylon picks. They are great overall . They grip well, I get good squealing pinch harmonics and are excellent for tremolo and alternate picking.

But I use them mainly because they are the most durable. I used to use 3mm Stubbies but I ended up wearing them down within two weeks. I used a fender pick once. I enphasize once because it only lasted one song.
