If any one is interested, I have a chord sequence for my version of open C - 6th to 1st - E G C G C E - which sequence is in addition to barre 5th and 7th fret.

The chords are F, G, Bb, Am and Faug.

PM me if you're interested.

I am confortable also in open D, and open G.

I have posted previously about DADGAD - I have, I promise you, revisited this, and am making an even bigger balls of things in this tuning than previously.
