THE GEMINI MIND - BLACK DIAMOND STRINGS

I have been using BLACK DIAMOND strings for some years now. Currently, I have been using their strings with Core Bond technology. They hold up well, feel good, sound good. Check out their string lines at www.blackdiamondstrings.com . Get back to me and let me know what you think. YOU ROCK, INDEED!! - The Gemini Mind (Mark Allen Lanoue)
