Morfiend,
I've had lengthy discussions with 33vortex, one of my squaddies who only flies 190's. He prefers to burn the forward tank fist. NOT for handling but due to the fact that, on a 190D in particular, the forward tank is much more likely to be hit. He says there is a "slight" handling advantage to buring the aft tank first, but doesn't outweight the risk of damage.
In real life, on most planes, you'd burn aft first due to CG concerns. Outa CG aft can make most airplanes very dangerously unstable.
