I normally use Mediums, but now I'm using/testing Elixir Medium-Lights (I think they call em "Light-Medium"). I like the sound of the Med/Lights and Mediums so I'm torn with what to use (i'll probably go Mediums next). But with the advent of the HDs I'll be interested to see how these play. I may hold off on purchasing some until I hear some reviews on how they sound with the GS shape. I wonder if they'd work against that shape?
Light-Medium .012 .016 .024 .035 .045 .056
Medium .013 .017 .026 .035 .045 .056
HD Light .013 .017 .025 .032 .042 .053
So their "Light-Mediums" are essentially "Lights" for the lows and "Mediums" for the highs. It seems the HD Lights took the opposite mashup. Mediums for the lows and Lights for the highs (with the G-string...hey hey...being the bridge at .025)
I'm sure it sounds great on the new 800s. But it'll be interesting to see how these play with any other guitar.
