What Grits said. A few more helpful bits though...
The G doesn't have power-boosted ailerons like the other 2. The J is actually pretty fast in a rolling scissors above 300mph. You can get alot of people to overshoot that way. The L has all the advantages, but people like to overlook it as a fighter because of it's reputation as a pork-n-auger dumptruck.
Gotta reinforce what Grits said, the key really is to use just half deflection once your first notch of flaps go out. It's really easy to overcontrol and wipe out any advantage. Tiny movements and the aircraft does all the work for you. Play around like that offline, dump flaps (@ 300mph down), use varying amounts of stick, and you'll see the difference. Once you see it for yourself, it's a whole new aircraft. Worked for me.
And until it's patched, don't get slow & past 3 or 4 notches of flaps. Used to be able to get down to 50mph, full flaps & gear down, now I'm falling out of the sky @ 130+
