I'm thinking about switching from rounds to flats soon...and I'm looking at these D'Addario Chromes for my Ibanez. They're cheap, and I don't think that it'd be a disaster soundwise, but I've never played with them before and I wouldn't know what they'd sound like exactly. Essentially...are they good strings? Any problems anyone had with them? If you didn't like them, would you reccomend any other flats?
