G6. Most challenging of the lot (with the Emil a close second), so more gratifying when you manage to hold your own.- oldman
K, G14, F, G6, G2, E in that order. They are all sexy.
I love the Dora too....if it wasn't for that darn glass radiator.
In terms of flight handling the Bf109F-4 was the pinnacle of Bf109 development. Obviously the later Gs and the K are better warplanes, but they are much less pleasant to fly.
glass radiator is much reduced thanks to Pervert's investigation and proof that a spinner hit was a hit on the radiator
