The Hurri I drivers for real knew they were out of the fight essentially when the 109F showed up in 1941. To throw guys in Hurri I's seems pointless other then to appease the Axis drivers. IIB and IIC were the order of the day.
The hurricane was out of the fight after the BOB, and everybody knew it. They moved it to second-line units, ground attack, etc. The problem is that in the real world it wasn't so... shall we say "effective"... as it is modeled in Aces High. In this game it has the potential to dominate planes "superior" (on paper) to it. The hizookas and the almost flawless flight characteristics coupled with the ahistorically fast rate of roll make it a platform that can take out even 109Fs, especially if given freely in large numbers.
I agree that the Hurr1 was out of the picture, but it technically wasnt, since sea hurricanes were war-weary airframes, based off Hurr1s. The Sea Hurricane IIC was a Hurr1 airframe with the wing guns changed out, but it still had the Merlin III engine.
The problem is we really don't have one of these in AH, and only about 400 .303-armed Sea Hurricanes, and about 400 20mm-armed ones, were produced in total. It wasn't very common in the overall war.
With all of these comments in mind, I suggested erring on the side of caution rather than on the side that might tilt things towards the allied planeset.
P.S. I'll repeat, "Oh, I wish we had an E-7!!!" (*looks around to see if HTC noticed*)
