I am an ancient Guitar Craft person who began using the New Standard Tuning (C-G-D-A-E-G) back in 1985. I find the New Standard Tuning excellent for melody work, open-voiced chords and ensemble playing. But I still play primarily in the Old Standard Tuning because of my accumulated repertoire in it, as well as its equal excellence in supporting melody work and ensemble playing, and my own ability to play open-voiced chords in it and its superiority for close-voiced chords and small harmonic intervals. So, horses for courses, as they say in sunny England.
For my acoustic guitar in the New Standard Tuning, I use the following gauges and windings:
Low C = .070 stainless steel wound
G = .050 stainless steel wound
D = .032 stainless steel wound
A = .020 plain
E = .012 plain
high G = .0095 plain
This requires a new bridge saddle to intonate properly.
