Three and Three Mark. I've been using Masterclass strings (also called Newtone) for three years now, and they make a custom set for me with a lighter treble and heavier bass.

I often play in dropped D, so in fact my sixth is even heavier. My set is 56, 45, 35, 22, 15, 12.

That's for my little Martin though. On my recently acquired Gibson J-50 I'm still experimenting.

Never ends does it?
