Nicely flown by all. As many have said, I would have pressed the fight early on. When outnumbered you need to even the odds ASAP. And yes....you gotta hit the shots when you set em up. I think gunnery is about 50% you got it or you don't, and 50% learned. You had 2 shots early in the fight that you couldn't afford to miss...IMHO.
I too would've taken the fight low along with pressing the fight a little more. Get those ponies low and slow and it's a different fight. I'm not a great 109 stick but that would be my approach.
