In this situation, I can suggest another tactic. If I am in the La7 and have an F4 behind me say 1.5K, but not closing, but I want to kill him, here is what I would do.
Go into a gentle turn...and watch the F4. Most likely he is going to take a lead pursuit and begin to close. This is what you want. Keep the gentle turn, and let him close. As he gets closer, pull harder, still watching him from the forward view. When he gets to say 500 yards or so, maybe a little less, reverse hard and go into a barrell roll. The size of the roll will depend on what the F4 is doing. Chances are he just extended thinking you did a hard break turn - little did he know you are right behind him...rolling around him as he flies right through your barrel roll.
Make sense? If not, shoot me an email, nimitz@huckabay.net and we'll head to TA and work on it.
