Im in Australia, but I've got one or two, maybe 3 XR-E 5A tint Emitters in the Q4 bin (as high as the XR-E neutrals ever went). They are definitely neutral tints, but to me seem a little on the pink side compared to midday sun in australia. This is within the definition of what a 5A tint is I believe, however this is great for outdoors, brings out the browns really nicely, think of it more as a tint slightly toward sunset, when everything looks better!
I can only say this because I also have 4C tint XP-G emitters, which by definition are further from "neutral" and are more green, but appear more "neutral" to my eyes here where I live.
Anyway, I've got some the emitters available, and I've actually also got 16mm boards, which I can flow the emitters onto for you if you want. Let me know what you plan to use them for.
