Personally I love them. I use the Di'Adario Chrome 7's with the wound G. The bass sound much more honestly bass-y and the over-all tone is far warmer. So if you are wanting a darker tone but drop tuning doesn't suit you, give them a try. Sure they are a lot more expensive but they last till they break, pretty much. Unless you have highly acidic sweat. Thomastick is my prefered six string flat wound but I don't think they make a seven string set.
