Best 1 on 1 I had was a few years ago, one of the first times I flew the '51B. One of the Finns (I've flown beside and against him many times, but his names eluding me) caught me in his 109G2 in a climb out to sea, and we commenced to zoom, turn, merge, dive, and repeat for about ten minutes. He got me in the end, but I got to try out just about every trick in my book in a plane that ended up being one of my favorites, and I also got to see what a 109 was really capable of in the hands of a pro. I wish I still had the film, I did for a long time but lost it when I had to reset my seystem a month or so ago.
