I quite like fighting Brewsters, at least the ones I encounter tend to stick around and duke it out to the bitter end.
Me too, if they are really high and dive on you setup a reversal as usual then extend away, drag them out and club them over the head when you have more E than them.
If they have a similar amount of energy just E-merge them up for a rope and bnz them to death. They can't run, they can't hide.
Even in my Spit I can't stay in a sustained turn fight with a good brewster pilot but the same goes for a Zero. Just adapt your tactics to suit the situation that presents itself and you'll be swatting Brewsters like the pesky little flies they are in no time.
I think your biggest issue junky is that you love to furball and Brewsters because they can't catch anything (see zekes or hurricanes) end up piling into a dogfight and latching onto someone already turnfighting. This is bad SA nothing else.
