I'we been using steel rotos 66 swingbass for about 10 years, tried dadarios, warvicks, fenders, yamahas, earnyballs... Since I'we tried DRs I'll never look back. Sunbeams for my jazzbass and hibeams for my 5string. Also using dadario chromes flats for a fretless and another 5string, but that is a whole different story, in a good way. For rounds DR!
