I've been trying different things, I like defense formations so it works for me. It is just a slight variation from another one where I put 3N on back line (dubbed the T-Shirt), these aren't standard, but then they have to guess what will counter it.

Also if I move guys around it's Maple Leaf... or make a sub and have 4 1 4 1, etc. I like moving guys around for more defense or offense depending how the match is going.
