I'm very picky with pics. I don't like fat or small or tortex pics. After trying maaaany pics, I realized I prefer the sound of metal pics. I tried some and I like this http://www.thomann.de/gr/dunlop_stainless_steel_051_pick.htm the best. It's thin and comfortable for acoustic guitar and chords but does not bend like thin pics so I can play from blues to thrash... arty07:
I have a DR stainless pick. I use it for solos sometimes, but I don't use it too often because I'm afraid of putting nasty scratches in the top of the guitar. I don't like it for rhythm playing at all.
Tech at the local shop makes some picks out of scrap CDs. For totally clear, you can scratch the label off or use one of the protective discs on the top of a blank CD spindle. Cut down to size and file the edges how you like! I imagine it's pretty similar to these picks.
