If I had to say so, I would think JT Style Pickin (more well known chords) and Amazing Grace except for that shift right before C9 are probably (at least to me) the easier of the lessons. (as pertains to the fingerstyle lessons)
Btw: What might you be doing right before that C9 chord fingering on Amazing Grace, you do some kind of
slide right there, not really getting through my thick skull.
