Crystal targeting matrix: anti-flyer?

DISCLAIMER: this is probably going to get FAQ'd.

 So with the key phrase being "full ballistic skill" , following RAW we can move tanks flat out and shoot flyers as if we have skyfire.

Applications can be a fire prism's str9 shot, a falcon's pulse laser or a waveserpent's shield. Does this solve the anti-air issues of eldar? Not really, at 25 points and "one use only" it's not exactly the most reliable investment.

Thoughts?
