How's this for a map?

Bases will be at the right side and the flags would be at the left. Of course, in this map, swuvels will be faster and flags will give more points. Might even increase the gameplay time.
@Pie Crust If you're planning on isolating the position of the team flags from the corresponding bases, I suggest using a neutral flag spawn instead. I can see it becoming a nuisance for players, especially if team members want to camp by the flag points. If you already have a manageable distance between the bases and a possible flag point, making one neutral flag point on the other side would be better than having two separate team flags for each to defend/capture. But otherwise, the new map concept in general looks pleasing all together.
Besides the new map design, the current one that you are hosting is also nice. I personally enjoy the nostalgic feeling I get playing at your server. Although, I wouldn't mind building a more detailed version for you. I'll have it done by today and I will link you via Dropbox when completed.
If you would like a nice skybox to go with the map, I have a vast variety for you to choose from; the same goes for music. It's completely up to you though.
I rate this a 10/10, well balanced.
