This might only be my experience, but when fresh, these strings are the best strings for bending I've tried, and sound great. They really are slinky, and for a period of not more than a week of playing they're excellent.
Then they promptly start to oxidize, sound tinny and lose elasticity. But they're the most comfortable strings to use while they last. If I were a professional playing a tour where minions change my strings before each show I'd use these (or maybe the RPS version of these). As an amateur who's not rich, I have to think of alternatives. I usually gravitate between these and D'Addario EXL 110 strings, which last longer but are less bendy.
Again, maybe that's just my experience and my hand chemistry is what's causing it. But I've heard others describing the same issues.
I've been using these a lot for more than 10 years now - I bend a lot so they're handy.
