Well, I ran mine with 3 ants and 2 Block Eruptors but whilst it worked, it wasn't stable. The BE's kept starting and stopping and the Ant's weren't mining at full speed.

Perhaps BFG miner hands them better but id say to avoid it to be honest., bearing in mind it would take 6.5 BE's to reach the 2GHS that 1 single overclocked Ant can create, you only need 8 Ant's to surpass the speed that 49 BE's can hash at.
