Many thanks.
No the symmetry is only if you accept archers and cannons are "the same" and wiz towers/mortars.
I then did something weird by swapping the air defences with wiz towars
I then stuck the TH inside because I was ticked off by getting so many free shields and no proper attacks!
At one stage the outermost parts were two 4x4 walls rather than one big 4x18. I had the tesla towers inside the gap.
Speaking of which, two of my tesla towers actually live almost exactly under the two blue arrows above. I am hoping people assume they are in the three/four obvious spots in the outer walls.
Food for thought though, I really value your opinion in particular
