Merci mcmoo, just the sort of concrete technical info I like to have. Absolutely it's personal, the instrument, the sound a person likes, the price of tea in Oslo -- but I like having the technical stuff clear, anyway, going in. After all, in the end, I'm gonna use what I like, not what formula alloy I "should" use. I picked my guitar because TO ME, it stood out from even several other very pricier brands. I expect I'll settle on some type of strings eventually, just the same way.
