The N1K2 and Hurri 2c.
Both formidable planes in the hands of skilled pilots. Unfortunately mostly flown by newer guys, or guys who have been in the game for a bit and still get their kicks from HOing guys. Especially the N1K2 with the heavy ammo loadout it has, makes for a flying WW. Everytime I see one I try not to even get close to the front because I "expect" the HO, same with hurri 2c. Other planes I will take my chances that someone other than the aforementioned clown is flying and actually wants to enjoy the fight.
