How would you configure 3 antennas for high density tower?
3x Dual-chain radios @ 10Mhz
3x Dual-chain radios @ 20Mhz
6x single-chain radio @ 10Mhz
6x single-chain radio @ 20Mhz (1&7 / 5&11 / 9&3)

I’m looking at a tower with 6 sectors at 10Mhz each (3v/3h). Here’s some stats on one of those sectors, the others look similar. There is a total of about 170 subscribers right now.
802.11g - 4.5/9/18/24/27 (10mhz rates)
30 Clients (3@18, 5@24, 22@27)
18.9Mbit/s interface potential (based on association & coding rates)
68.5Mbit/s demand potential based on client-side queues (tx/rx =38.8/29.
This AP is oversold by a 3.6:1 ratio, but performs very well.
We would like to increase the total capacity of this site by deploying 5Ghz sectors. However, in order to do this, we would have to consolidate our 6-sector system down to 3 sectors to make room. The new antennas will be dual-polarity and they will be shielded.
The only question remaining, is to come up with a radio configuration that will provide the highest density possible without sacrificing performance. How would you do it?
FWIW, here’s a diagram showing how I think I’d deploy 6 independent radios @ 20Mhz:
