Air Sweeper

Whats the best way and most effective manner to place the air sweeper in your base?

Use it for mind games. Place it to direct what side your attackers drop their troops from.

I've seen many examples. the best? beside the townhall if you are using it for a war base.
And beside the center DE storage for a farming base.

Make it cover two air defenses.

I cover my aq and 1 ad

In war bases, you know that the 2 AD closest to the queen have a high probability of getting wiped out by the kill squad. so there is no real point in getting it to protect those side two so the sweeper should cover one of the two remaining AD. Pick one and put all the air traps near the remaining AD.

I centralise the sweeper. I' not sure how critical that is though
