Having used lesser strings for years on acoustics, my son gave me a present of Elixirs, and I have NEVER bought anything else since. I started with 11's, which completely transformed the sound of my G-series Tak. The G and D of the cheaper strings had always been much too quiet compared to the outer strings, which necessitated "digging in", therefore breaking strings before they had completed one gig. Elixir 11's tended to break after 3-5 gigs. These 12's seem to last forever, and never lose their bright, balanced sound. In short, they sound better, last longer, and feel smoother... I couldn't recommend them more highly!
