All 100s are the best for online dogfights...
Eric Brown's settings are the best if you want to get the "feel" of flight.
It may seem mushy and odd at first, considering that the highest values are about 30, but rapidly turning a heavy aircraft controlled by cables and pulleys is not easy - the maneuvers we pull in the game would be nearly impossible in a real aircraft. You would need the arms of a gorilla coupled with totally inelastic control cables.
Also keep in mind that a real plane has a stick which is roughly 2 feet long, and considerable "throw". Our joysticks are maybe 6 inches long, with maybe only 2 inches of travel in any direction. Couple this with a lack of force "feedback" (80+lbs in some planes/situations!), and you're suddenly piloting a fly-by-wire jet when you're using all 100s. (No wonder the La-7s are "uber"

)
Still, it's important to be able to go to maximum deflection of the control surfaces in order to survive in this game, especially online. I choose to fly with a compromise, either a linear scale (10-20-30-40-50...100) or, more often, with the quadratic scale (1-4-9-16-25...100).
I save Eric Brown's settings for joy-rides
Hopefully DT's plan to implement multiple joystick profiles for a user will allow me to switch back and forth on a whim
