I installed these strings on a 1/4 size guitar. I used the nylon G3, but it broke at the saddle end while tuning. As the saddle was new I suspected that the front edge might be too sharp, so I smoothed it slightly, replaced the string, and tuned it up very slowly. This time it reached the correct pitch without breaking, but after about a minute of playing it broke again, this time at the other end -- evidently the saddle wasn't the problem. As an alternative, wound G string is supplied I then installed that and tuned it up. It was fine and was still OK several days later.
I expect Hannabach would have supplied a new G string if asked, but the owner of the guitar is happy with the wound version.
Perhaps if I'd stretched the nylon G string over a longer period it would have been OK -- who knows? But it does seem to be perilously close to breaking point when fully tuned.
Now the pros: The strings produce a good sound, even on a cheap 1/4 size guitar, and the wound G string adds a nice resonance. There seems to be little of the usual tuning discrepancy between open and fretted strings. This may be because the strings to have to be stretched a long way to reach the correct pitch, and consequently the extra bit of stretching caused by fretting a note does not make much difference.
