My Brick Wall is Jacob Arney

Good post I, like you, always have 5-6 defensive players on the same instructions in most of my tactics. They are quite different from yours though, but I do get a lot of clean sheets as well, once my players are of a certain standard.

In the office now, but will try posting them when I get home. It could be interesting to have a "brick wall defence"-discussion, where people share their defensive setups.

Again - good work on making this thread. I might test your approach at some point.
