Almost every single collision I'm in is with a Spitfire. The Spit jocks have a real bad habit of turning into you when they are out of moves.
Sometimes I wonder if it's just too much plane for some. These guys fly these things because they turn well, but most don't turn them when they need to. They'd rather save the flicking and flopping for when you're on their 6. 
Anecdotally, I have to second your view - and in fact, it happened tonight. I was all over this clown in a Spixteen. I was using my G-14 to dance on his head and he couldn't fly his Spixteen well enough, apparently, to realize that , despite his e deficit, he probably could've erased my e advantage with a little judicious climbing. Hell, after my first pass on him, I blacked out on the pull-up long enough that he could've probably either killed me or climbed so far up my poopchute that he could've tasted my breakfast. Instead, he just kept turning, low and slow like a good short-bus candidate. On the next pass I came down with a little less smash and relieved him of an elevator. Mind, I'm doing this in a gondo-laden G-14 and I'm no great stick (which should tell you his quality as a pilot). Anyway, once the left elevator's gone, he's sort of running out of options so on the next pass he turns right up at me, I hit him, and he goes down. Within an instant after that, a wirbel below kills me. Object lesson: when the pilot sucks, watch out for the ho and flakker.
