Dunlop Ultex Sharp, I use the 1.0 and 1.14, I think they are great picks. If you have not tried them, give them a shot and see what you think. Before these I used the Tortex, close to 2's, I think like 1.8 or around there. I really, really like the Ultex Sharps they are by far my favorite ever.
A friend of mine swears by the Pickboy's, they make a bunch of different picks and I don't know which he uses, but he has given me some to try and they were pretty cool but the Ultex Sharps were better for me.
