I used Augustine strings for my 6-string acoustic..
..usually buy a whole set when I restring my 12-string
sounds much better with a full set of new ones
- if I just change one or two, it goes out of "balance"
can't remember what type I've got at the moment, as
they were bought for me by a friend..
PS. my son uses Ernie Ball super-slinky's on his lectric..
