I use BAM with 3-4 giants thrown in. I don't use the minions unless I have to.
Barchiing is a good method but it really takes the right base. I havn't really done it in M3 because of all the high lvl archer towers and morters. I use giants, wallbreakers, goblins, archers, and barbs. With that I will mix in heal spells+hero's if necessary.
