The last poll broke after I edited it (thanks Neptune :P ) so here we go again....
I do not claim to agree with all of these choices but they appear to have the most public appeal. So yeah.
The important thing to note is that the universe name must describe only the Arrow and Flash series while not being inclusive of past live action shows; a name that is too general could be mistaken for including other shows and entities that were not meant to be included.
If it isn't in the poll, that means the name is too broad or is functionally unusable in some way, shape, or form.
