I like to play with this tuning. It forms the basis for the high strung, reconfigured Backpacker I use as a 'poor man's bouzouki' - and I occasionally use it for a song or two on my guitar, but it's a bit impractical to retune during a set, and it's hard to dedicate a guitar to the tuning - so I use it mostly for fun. But I love the possibilities it offers. The inside four strings use (G tuned) banjo chords, and the 6th and 1st strings can be easily extended. You can pick out melodies up the neck, with one and two fingered chords against the full open string accompaniment.
It's so close to the popular Celtic tuning, DADGAD - the only differnec is the 3rd string is tuned 1/2 step down for D major - but there is a world of difference in the sound.
