I just watched the 3 films, and I totally agree with Hooligan about the Hog clip. You might as well of sawed off your own tail with a hacksaw. The hog had more E to start with coming from a higher alt (remember, they are heavy birds too), and the second turn you made gave him a great shot. I might have tried to continue the first turn another 90 degrees and extended for a little alt, making the hog come around the full 360 lower than you. (Unless he pulled up vert over the top

)
I saw a short Pony vs Spit fight in film #6, not a Yak. You won this fight purely by having a lot more E than the Spit, and getting a good surprise bounce. Even though, there were a couple of close calls, where you gave up good position. Patience is more than a virtue in the Pony, and the only hurrying you do will be toward a smoking hole.
The N1k fight shows this to an extreme. I lost count of how many times you had a great chance to extend, climb, and reset for a good attack, and you reversed right back with him co-E. In the Pony, if you're fighting fair, you're outnumbered. Now, granted, I did see some amazing pulls by the N1k, but you were riding a pretty rough road yourself, and blowing a lot of E on low probability passes. I would have tried to get some separation, and climb up, then reset for another slash. As a side note, your after flight "salute" could use a little work if you want to make friends

I'm not an expert at anything about AH mind you, but a lot of really good pilots have tried (with little, but improving result) to teach me how to fly in the Pony. If I'm wrong about what I said, I hope they'll steer you right.
