I personally LOVE bam. I tried it once and never stopped using it :)
The great thing about bam is it uses ALL 6 barracks making it a very quick training time.
Here's what you do - look for bases with all the resources in the mines and pumps. Take them down using as little troops as possible.
Make sure you are always training troops - this way you will get extra troops while raiding. You should have 1 barracks full of barbs, other 3 full of archers. dark barracks should always have minions.
I generally attack with only about 100-120 troops. If you use troops efficiently, you can raid 2-3 times before having wait again.
I can make about 2 million gold an hour with this since it's so fast.
Hope this helps and good luck farming!
