Well, here are some classic mistakes often perpetrated by new folks, and perfectly displayed. A 1k alt advantage doesn't gaurantee an E advantage. If your opponent has been grabbing to get 1k over you and is flying at 130 knots, while you are cruising in your Hurri at over 250, I'd say he doesn't have an E advantage at all. E is not only about alt, speed is important as well.
If you want to exchange a distant HO, so be it. You're in a plane w/ hispanos... duck under like you said.... that's smart.
After that I think you go astray.
Why pull up right in front of him? Yo'll give a quick minded pilot a snap shot and if he truly has an E advantage, and in your Hurri, by the time you get your nose around, you'll be looking at the tail of a plane that is too far away to get a good shot at. Additionally, if you do this to a pony, G10 or other speed plane, you'll find yourself roped and slow to boot...utterly defensive.
After the merge, why not get your nose down just enough to get to good maneuvering speed and force your opponent to reverse and go after you? Especially if he's in a speed plane, like Slo said: once he's on your 6, you've got him right where you want him. Perform a displacement maneuver of your choice, make him overshoot, then blast his tail off. Gofaster's move is a sucker move, he is surrendering alt in an effort to force his opponent out of his manuevering envelope. Against a smart pilot, Gofaster will find himself lower than his opponent and defensive.... BnZ'd to death.
