I have some Elixir Polyweb 12-53s I was going to try. I've never used the brand or coated string before. I also have some Thomastic-Infeld " Spectrum Bronze " strings which are 12-54s. ( They better sound good for the price ! ) And.. some John Pearse Phosphore Bronze 12-53 stings. I really wasn't sure which of my acoustics were going to get what string, but I figured I should at least try strings outside the Ranch Dressing D'Addario stuff.
