I very strongly suggest that we use a geometry guaranteeing that a base will flash. That will bring in the players. Lack of players is the current problem with Trinity TT, as you can't tell if someone is in there. In the worst case, even if someone merely "sits on the base", it generates an interesting fight. However, in Ozkansas, once people are in there, they typically go offensive and leave the bases, which is the ideal we are striving for.
One way to do this, Greebo, is perhaps to put 3 Vbases in the center, identically spaced to what we have in Ozkansas TT. (In other words, leave out the center town). The first player in will be able to generate attention by starting to capture one of these Vbases, which will cause them to flash. Radiating out from this Vbase there should be a series of additional Vbases from each country, spaced as in the Ozkansas TT. Leave out the Air bases, ring with mountains, and make the whole thing relatively distant from any air bases outside the mountains. The Ozkansas layout gives plenty of "room to fight", and is quite interesting to play in. I don't think it loses anything by leaving out the center town. It's main problem is that it's too easy to fly AC to.
