I like em too, but once I tried DR Sunbeams I never looked back. They're the same as DR nickle Low Riders, but they have a round, rather than hex, core and seem tonally richer, a bit warmer, and more complex sounding with no loss of articulation. The only caveat being that they have less tension, so they're not ideal with shorter scale lengths or floppy B-strings.
I have been thinking of trying them but it is the tension of the hex core that keeps me comming back. I do have a 35" scale so the round core should not be a big issue.
