Probably not for everyone , but I think they are great, great feel and tone,, take a while to mellow out fully but when they do, there great,, I put a set of 12's on my guild f30 aragon changing from d'addario phosphor bronze which I have been using for years and they sound great on the the guitar. once they get mellow they definitely have a longer life then normal strings, It's all about experimenting really, they may not suit certain guitars etc, but on my guild I am very happy with them, I would recommend trying them and see if you like them
