Favorite : Dunlop Delrin 0.96 - Magenta/Dark pink. About four weeks ago I found one of these picks while looking for something else and I have been reluctant to put it down since. It has enough weight and thickness to keep up with and sound authoritative while tremolo picking, and it still allows me a nice dynamic range. I cannot find these in stores. I only have one. I think (hope) that I can order from the website though.
Used to be favorite : Tortex 0.88 - SeaPuke Green.
In A Pinch : Dunlop Gel X-Heavy (1.14 I think...) See-through yellow.
Love/Hate : Gator grips. Feel great in hand, good grip - but - sounds "scratchy" when plugged in.
I Strum With (any) Fender Medium - tortiose shell, cali color, etc...
