DR Strings Black Beauties BKE-9/46

Bought 2 of these Black Beauties to black out 2 of my guitars. Although expensive I thought I'd give them a try. They look great after changing the strings and sound good as well. Had read other reviews that pinch harmonics may be an issue but found them to be fine. Only problem was after the first rehearsal that the black coating came off a lot and left dust between the neck and bridge pickups. I think that these may be better for maybe just photographs as the extra money paid and one use with the coating coming off doesnt seem worth it for me. My normal choice of strings are D'darrio NYXL's which are a few ££'s cheaper. I will revert back to these once the strings need changed. I suspect after more playing the coating will deteriorate more and the strings will start to look even worse.
