I really like the DR's, well the round cores, whether SS or Nickel..... I like the lower tension of the round cores. Kind-of evens out the feel, switching from a long scale bass strung with round core DRs, to a short scale strung with hex cores. I've got a Gibson 2017 EB strung with Sunbeams and Black Beauties (which IIRC is a Sunbeam under the black coating) on the 'bird. Sound wise, don't sound a lot different to a nickel Roto, EB Slinky, or D'Addario XL to these deaf ears.... For me it's all about the feel. I dig the feel of them.
