D'addario is what I've always used. Always have and always will love phosphor bronze! A set usually lasts a long time for me, so this pack of 3 will last for a while. I personally like the light gauge for its clean, crisp sound that I have always loved on both my Yamaha gfx and my Ovation. My neighbor uses the mediums that are sold on this listing, but I would recommend the light gauge as a better overall sound. Thank you D'addario!
