As stainless strings enthusiast I must admit that those are one of my favorites, but they have a major drawback - they don't last long.
Pros - aggressive bright sound - lots of zing when fresh - vacuum packed - silk wrapped at the end to protect the machine heads
Cons - don't last long (after a single 40 minute gig they went almost completely dead, and I don't even sweat much) - non tapered B (issue for some) - a bit rough on the fingers - unusual A string thickness (0.80)
Just love Roto strings. Love bright sound. Some people suggest they rip up frets and the brightness doesn't last. I don't agree with the ripping up of the frets. The brightness may not last quite as well as some strings, but the sound once they have settled is very good.
