I received a racquet (K Tour Team FX) to restring with really old strings that I'd like to identify, so I can put something similar back in. The only thing I can make out for sure is "Wilson 16" and right after it, it looks like a "YGN2" or "Y6W2" or some combo like that. Anyone have any idea what string that is? Wilson's site didn't list a recommended string that I could find. And I'm not sure if these are the original strings anyway, although they were notched really badly, so they might well have been.
