Karnak,
Are you high? Saki said that the N1K2 was crap not the Hayate. You should really check your source. I got mine from an interview with Saki himself.
http://www.danford.net/sakai.htm Look down in the interview. The subtitle of "On IJN leadership".
The Ki-84 is without a doubt the finest fighter produced by Japan during the war. Excellent maneuverability, excellent power to weight ratio, good guns, good speed (for a Japanese fighter anyway) good visability, good armor, self sealing tanks, etc......
