While I love the tone of round-wound strings, I also love the feel of flat-wound strings. I grabbed a set of these HALF-ROUND strings for my new bass in hopes of having the best of both worlds. So far, so good. And, I'm hoping to get a good life-span from them, but only time will tell. With the D'Addario brand's long legacy, you can't go wrong. Thanks D'Addario for offering this best-of-both-worlds set of strings!
