The lack of string noise means the following

But with these half round strings, you can do the chord slide with maybe 1.1X to 1.2 pounds of pressure and not hear string noise (you'd tend to increase the pressure a little on slides to help maintain sustain during the slide)

much less tension than flatwounds and wiithout the string noise of roundwounds, though still not as bright as rounds

Cuts out a lot of the string noise that round wound strings tend to have

Great for less string noise

With regular wound strings, if you need to press down with X number of pounds of pressure to fret a chord, you'll need maybe 1.5X or more pounds of pressure to be able to fret and slide the chord without generating audible string noise

But i wanted a little more r&r tone from my Epiphone Casino, a little brighter
