I got some. Strung them up on my Les Paul, PAF neck and JB bridge. Into a Valveking. That's it.

The strings feel more malleable than normal Ernie Balls (switching same gauge nickel to cobalt) on the lower ones, but the top 3 feel much tighter.

The sound. They are slightly louder. A bit clearer in the higher strings and when using chords, but the bottom end is muddy as hell. They sound good clean, but heavy BR00TZ distortion will make them sound like absolute mud. I can't EQ the bottom well enough to pull of a chugga chugga that's easy to get with nickel strings. Maybe they need a break in period? I dunno. I am not a fan of these to be honest. Don't see what the big deal is.
