I did a review of them on the AGF. I'm thrilled with these strings, but I believe they are very different. Be sure you try before you invest in multiple sets. They, without doubt, are different. I like them enough to have bought a pack of 12, and that's coming from a pretty confirmed Elixir/D'Addario 80/20 user. I know Martin is touting them as low-tension, but the tension chart shows them as similar to regular Martin light gauge, and I certainly don't notice a particular low-tension feel. I like a bit of tension push-back from strings, and these don't feel low push-back. That said, however, these strings are worlds away from a silk and steel feel.
