Psh, you can get 66 million on Hadaron's SBB with this setup:

Dual Hadaron (66 million from each Hadaron)

Griff (SBB)

Zedus (UBB)

Gazia (SBB)

Raaga (SBB)

Note that this was done a while ago, so with newer units you could probably go higher. I think replacing Griff with Avant and Raaga with Chrome would work.
