Nice guide!
my only problem with BAM is that it is very difficult to get any meaningful amount of de. And you need a lot of de and gold at th9! Otherwise, your builders and lab will go idle. There just is not enough elixir upgrades at th9 for the lab. Either let it go idle or start upgrading de troops.
edit and collector raids are not really available 24/7. There are certain times of the day where there is very slim pickings for collector raids. Also around update time the collector raids dry up.
