On the strength of recommendations here I bought some Newtone strings - and hated them. Guitar wouldn't stay in tune and the sustained notes seemed to bend. Gone back to my Earthwoods and both me and the guitar are far happier. Didn't particularly like Elixirs, either.
Oh, and I play a Ralph Bown koa guitar made to be like a Martin 0028, if that's relevant - and maybe I don't have string-destroying hands!
