I have played 11's for around 10 years, great tone, but can be hard on the hands, bending strings etc, so I decided to change down to 10's. They improved play-ability tremendously , but there was something just lacking tone wise and also the feel. I I found these 10.5's and they are just perfect. !! I have always used D'addario, they never fail in quality. cannot recommend these stings enough if you looking for the feel of 11's with some extra play-ability.
