I got a set at NAMM, and threw 'em on my new Low End/Benavente jazz bass...I've been a big fan of DR Low Riders for quite a while. After hearing these, I'm hooked. I don't know how long they'll last, but they have the tension of stainless, but the slippery feel under the right hand of nickel. The E string has an exposed core, and really helps the note speak quicker. Overall, a really mid-punchy string, and a GREAT feel! Gobs 'o tone. Anyone else here try 'em? How is the longevity (if you keep your hands clean)?
