I play 3-4 nights per week for last 30 years, I've tried a few different brands over those years but I keep coming back to these. I HAVE NEVER, EVER, BROKEN ONE OF THESE DURING A GIG! And that's saying something.
The 12's are a well balanced set giving the right amount of top/mid/bottom tone for playing all styles without changing instruments, a must for a gigging musician. I get three nights of bright, clear sound and I can stretch to four nights if I'm not feeling overly pushed. After that they will start to loose their 'metalic springiness' but are quite playable if your not too fussy.
Well packaged and sealed, I buy 20 sets at a time and the last set is as fresh as the first.
All in all these are my go to strings for acoustic and previously electric gigging.
