I'd go ahead and use this one. Since that post I tried a few more things, but they didn't make it sound any better, I think this latest version is the winner.

As usual, feel free to also change the filename if appropriate when adding it to the game.
Related note (no pun intended): IMO I also think this one fits better in the game than the 1st air combat tune I put together in the other thread, although if you want to also put the 1st one in the game (for any purpose, not necessarily air combat) then go ahead, otherwise I'll save it for something else. As Surrealistik said, the other (first) one does kinda have a problem fitting in with the other tracks in this game, and I think he may have been right when he said it would work better for a "Mega Man" game. Still, feel free to use it for a cinematic or something else.
