Ive used nickel and stainless Lo Riders for many years. My favorite all-purpose rounds, with Roto Swing Bass way up there as well, although they are a little more raw-sounding, which works very well on some basses. I used Hi Beams for a short time, and although they seem like excellent strings, better than most, they dont fit my style. Between the LR nickel and SS, I prefer the nickel. Somewhat stiff, but easily manageable, great full and very even tone, sensible highs (as someone else here had mentioned years ago). Less zing than many strings, but plenty treble. The SS are just a little less middy than the nickels. Long-lasting, with a somewhat gradual degradation in tone over time. I only played one set that I can actually say “died” on me; that was many years ago, and they were probably years old. I admit that I’m somewhat ham-handed, and their rigidity helps to cover up some of my laziness, although I could adjust to lower tension strings (I have no problems with the low stiffness of TI flats). I agree with Michael T that the nickels are somewhat refined and neutral (but not so refined that they can’t rock hard).
