I can't begin to say how disappointed I was in the tone of Black Beauties when they first came out. I had used a few other DR strings prior to that and had high hopes, but they just sounded anemic. I have enjoyed the tone of Fat Beams, but generally am now using Chromes to get a reasonably present and full tone without the round wound fret noise. I may try a set of these coated strings if the reports remain positive.
For the few people who believe they have had a bad string or two in a set, has DR stood behind them for you? At $40 or so a set, I'm not likely to try again on my own dime if I get a mis-matched package. I probably should have tried to contact them when I got those awful Black Beauties, and then I'd know how their customer service is. Instead, they got dumped after about an hour of continuous and unpleasant attempts to dial in a reasonable tone.
