I don't furball much but when I do I like to take the tough ones or the pickers.
FM2 are great
F4F's are slow but not bad on the outskirts where you can extend and come back a few times.
109f on occasion, very nice plane
LA's, how can you not like 'em heheh
I'm interested in the Ki's and need to learn the F4U's but don't see them as furballers (F4U's)
I see very few 190's out there unless there flying high picking other high flyer's.
I've seen so many planes that people say they like to furball with but expect if i was to look that up I'd find they rarely take them for anything. Bunch of smoke blowers. p40E , p47's psst
