I use for many years the Gibson's Pure Nickel Vintage Reissue 11'', but I had problem for some period to find them as they were out of stock. Since I don't like D'addario and Ernie Balls at all and I have already tried Fenders with not great succes, I tried the GHS as an alternative. It's a nice set of strings, with good balance and a good midrange responce very close to my taste. I am still not going to replace the Gibsons, but so far it's the best alternative for me.
