Fingers, slap(/pop), and double thumb(/pop). Right now I'm playing mostly double thumb/pop because it is the most fun to play IMO, and gives a nice funky sound. There was no double thumb option, so I just clicked Slap. I can play with a pick, but I hardly ever do mostly just because I don't really want to... Fingers would be my 2nd fav way to play, and I'm trying to fast with three fingers, instead of just hitting on the down and up with my two fingers. Then slapping, which was my favorite way to play until I discovered double thumb.
