Tried these out. Soundwise they were really good, but the feel was to sticky for me. Don't know if it was that the winding seemed not as "close" as other flat wounds I've used, coating or other aspects, so I sold them after a couple of weeks. I bought a set of GHS brite flats instead, which was perfect for me. Strings are as subjective as it can be. For me - these wasn´t the right string, but they may be for you. Despite my disliking I have to rate them according to sound and quality, and can´t say that Ernie Ball doesn´t deliver.
