Ernie Ball Earthwood 12-String Custom Light 80/20 Bronze Acoustic Guitar Strings, 10-48 Gauge (P02013)

Size: 2 Pack What does it mean? Is it on sale you can get 2 packs or "2 pack" means for something else? Thanks!

I am thinking of getting this extra light set for the reason that it is easier on the fingers. is there better alternative to it? f.e. silk $ steel?

Pros/cons of light versus medium for sound and action? i'm 70 about to go back on a friendly stage after years away using a taylor mini accoustic

Trying to get something for my husband. I see the one labeled 12-string. But he also needs a 6 string. Is that just the basic package?
