Rare Greek Variables

The varkappa and the varpi are just calligraphy versions of the regular letters κ & π, so I would avoid them. Also, the ς is just the form σ takes when at the end of a word, so I'd avoid that too.

And I don't know why anyone would use the uppercase Ξ (Xi) when the lowercase is such a nice letter: ξ.

I like ξ! Have been using it in my paper. When presenting it, people have different ideas about how to pronounce it. Some say it like x-i, some say khi, and some try hard to say xi. I like the x-i version as it is similar to its latex notation \xi.

It seems okay to use both uppercase and lowercase versions at the same time. For example Ξ is a set and ξ is an element of the set.
