Looking at your video at the start of this thread Rob, I was thinking about the advantage with fingerpicking over pick for these chords you play. I tried a thumbpick years ago but they were all really cumbersome affairs that made it hard to pick the string the way I wanted.
I googled the other day and came up with this little gem. Its a normal pick and its a thumbpick all in one.
I ordered one(should arrive today). Looks pretty good as far as I can see.
This item looks like I can get the fingerpicking effect as in Pass or Taylor type of playing coupled with the normal attack you can get with a pick.
