I tried in the past the Pyramid Extra Light set (008-038) and I was very happily surprised, as they had great tone and they were easy to play.
With this set, the Medium (010-046), I expected strings that would be tough, harder to play (i.e. bend), but with better tonality. Unfortunately, I was disappointed.
They do feel sturdy, keeping the tuning well, and they're of course harder to bend, being thicker. But sacrificing ease of play for sound quality was not worth it, because, quite simply, the sound is disappointing. At best, they're exactly the same as the Extra Light set. But I'd even say they're worse, with duller sound and disappointing hue.
They're not unplayable, of course, but I just don't see the point. Next time I'll prefer the Extra Light set again, which is an awesome bang for the buck.
