D'Addario EJ49 NT Black Nylon Guitar Strings BNN-3T, Treble Set

Strings arrived quickly and on time. However, the high E string has noticeable intonation issues. This is my 2nd time having this problem with the black nylon strings.

I've tried a lot of strings, and good ol' EJ-49s seem to sound best on my guitar (and are the ones the maker recommends for it). I got the black trebles simply because they look cool, and also because I may record a video of a tombeau I wrote in honor of a good friend that recently died, so black is appropriate.
