They are not all that easy to master, for a fact. You would be surprised how far you need to lead a plane in a Perpendicular line of flight. The cannon shells slow an awful lot at that range. Like mentioned before, the LCD in off line or even with Morfiend is easiest way to nail it down. I am fairly confident you will go "DANG, its true. Have to lead a WHOLE LOT more". Heck, the targets are pretty much way out side of the sight box. I use the "Swing Through" method. I have better luck with Wirb that way, lots more than the "Constant lead" method. Sort of like shooting Skeet or Trap with shot gun. "Swing through" is sort of self explanatory. Now when I say "Constant lead" I mean put your sights where you believe they are going to be in. That is just the first step in this method. When you think they are going to fly through your zone, start turning the turret at same rate of lead. DO NOT stop turning it either. These turrets are not the fasted out there. Hard to regain any lead once you fall behind. You can tell if you need more lead, just watch the tracers. It is just that "Swing Through" is what I am use to. Shot a lot of Skeet, so its in my comfort zone so to speak. And YES, same rule applies to this method as well to some degree. You swing through the target and start shooting when think your target is in your zone, But keep swinging. Its that follow through, that can pay dividends. I basically swing through and keep shooting, sometimes speeding up my swing in process. This works better on further targets like around 700 as closure is faster than the turret and cant keep up. I just start my swing earlier, sort of a "Lead Turn" that you use in ACM.
