DR Strings Black Beauties BKE-10

I am a fan of DR string and they are still the only brand of strings that I buy, but these black beauties are simply just not worth the money.I bought a set and played them on my strat and the tone is super bright from the moment you put them on (not my preferred tone but not necessarily a bad thing) but darkens after a bit of breaking in. sadly its not only the tone that darkens, its also my strats pickguard and pickups since when play with theses stings, the coating on them comes off as black dust which really stands out and looks awful on a white pickguard, this shouldnt happen at all as the coating should stick to the strings at all time but since it comes off, the strings dont last particularly long, thus defeating the purpose of having coating on them. In my opinion, the black coating is just a gimmick, and a rather expensive one at that. I I do not recommend them at all, if you want a good set of strings, get a set of DR pure blues.
