The BAM tactic is an awesome resource getter. Sometimes you will have epic fails, but if you exercise patience in targeting bases you will almost always come out ahead.
Sometimes you can hit that [Next] button forever and it seems the server will just NOT give you a base with full mines and collectors. So also be on the look out for bases of equal, lesser, or one size bigger that are weaker than yours. Basically, just look for those unfortunate souls that have rushed their Town Hall upgrades. And just pillage them hard!
I am a new Town Hall 8 (2 weeks now I think?), and I find quite a few Town Hall 7s, 8s, and 9s that are in weak shape for a number of reasons. (Look for a post on this later) So I look for these also, while I am looking for those "gold mines".
I have a short video from a replay to demonstrate the type of base:
