Hard to find these in my neck of the woods, so finally ordered them to put on my loud and bright Arches kit F. So first impressions, they warmed up the mandolin significantly at the cost of a bit of volume. Do these change much after breaking them in?

On the subject of strings, I'm liking the Martin coated strings I put on my D 35. They sound and feel great.
