Thanks Fort. And thanks Michael...for keeping your temper in check when dealing with Phillistines.One more thing on the "index/flatpick" issue. I tried playing some of his guitar style with just an index finger this morning. After about 10 minutes it's not much of a trick at all. Perfectly valid, and when I hit the notes right, sounds like a flat pick or a thumb pick.
OK, one more little addendum to this. The man who (sort of) invented the genre, Charlie Monroe, used a thumb pick and finger pick, and he sure got around nicely.
