Firstly, I do not have much experience with 12-string guitar strings, but in terms of playability and sound these are quite good
The Ernie Balls feel really good under the fingers, are easy to fret and even bend, and despite being really light for an acoustic they have quite a good, loud and sustaining sound.
However, I pretty much never break strings, unless they are really old, but I managed to break the thinner G string on this - so they are quite delicate, so if you are a heavy strummer, probably they might be too light for you.
As a conclusion - I tried and I liked them, actually ordered a couple of additional sets.
