This is a fastest map I made with
- 30 stacked resources, 6 geysers, 65535 resources
- Centered bases
- Perfectly equal base sizes
- Enough room between Center and Geysers for Computer to place Comsat Station
- Enough room at the top and bottom bases to place a Center on the other side of the minerals (an Ally for example)

Unfourtinately, the chokes won't be equal (this is impossible). All bases except the middle two can be walled with two 4x3 buildings.
