For Supermans Speed 2: Add london, carpathian, discovery, and pbcup_pforest. (unless any of those maps are already on speed #1) Remove napalm and daylight. Add neon just for a day or a few days to see how it plays and how much people like it. No doubt they will dislike it at first because of its complexity and it is hard to navigate, but once they've played it for a good 15 minutes, most people from my experience have figured out the basic layout.
For Suprrmans Pub: Add pbcup_renoir.
For all your servers, change "Supermans" to "Superman's". It makes more grammatical sense that way unless you are talking about multiple Supermans.
