I think alot of you are thinking way too much about this.I play electric + acoustic guitars using guage 12 strings which do smart a bit during long sessions, but its not gonna kill me! sleep on it and im fine..meths barely works, and super glue?!?! im not buyin that one....back in the day peeps used to 15's and not whinge about it.I sacrifice having "sore fingertips" for the love of playing and after all when on stage all i think about is the sound not the feeling..that comes after.
