Grade-B
I think it was one of the better PTO setups. Those who mentioned seeing too many Georges, or N1k2s......... Remember the N1K2 is having to stand in for the Ki-84, Jm2, and N1K1 , as well. If not for the Ki-61, and N1K2 , everybody on the Japanese side would have been playing dodge ball against Corsairs, Hellcats, and Thunderbolts.
I thought the IJN/IJAAF, put up an excellant fight this setup.
