In feel and sound, after playing for a small hour or so, these are the best. I never use any other strings.
On a sidenote: the crisp sound reminded me of a walk on a winter afternoon, where you enter that small treeless patch in the middle of the forest and are suddenly surrounded by this ring of pines while treading on the soft yet slightly hardened first snow of the year. Softly sinking the first foot into the crackling fluff, packing together what is soon to be your first hurdled projectile of this season, you feel the same physical sensation as when you were 5 years old: that is the feeling of pure blues strings.
