I almost solved the NCEES Pencil Color Equation! ..... but not quite

[Orchid PE]

I believe everything pre-2005 was still using a rotation of swan, goose, and turkey quills (depending on season). Before that it was Egyptian reed pens.

What do you think?

Personally I love the new pencil style. The grip is really comfortable and I never had an issue (either this time or April 2021) with the eraser or running out of lead or anything.

The grip distracted me a little when while thinking or reading the problem I scratched my nail on it and the sound is a little annoying
