I'm looking to move from my current ZR3's to LI. Will I get enough coverage from the dual unit or do I need to go Quad to be bulletproof? I'll probably move my existing three ZR3 heads to the rear, but that area is a lot of square feet to cover. I've got three new heads that I will be installing because the ZR3s leaked (again!) and they sent replacements. Maybe the ZR3 unit works where it doesn't rain.
Any ideas? I would love to hear that the Duals would work price wise, but let me have the bad news if Quads are what I need. I am more concerned with frontal attacks but I have personally seen Plano PD (DFW suburb) shooting rears from a bridge, hence the moving of the ZR3's thought. Has anyone worked with a Superduty before?
