Why not spray before the IC's as well as close to the TB's? I've never set up an aquamist system before so I'm not sure if there would be any limiting factor as to why you couldn't spray in two locations of the same path of air travel. The only thing I could think of is that you would be limited to the amount of water injected overall and injecting in one prime location could be more efficient (just how much...?) than spraying a lesser amount in two.
