My first choice is the F4u-1A. However, from experience in WB, when you are flying the Corsair, especially for CV OPS, and with all the non-historical matchups against all the cannon-armed Spitfires and FW's,and the heavily armored P47's, F4u's and F6f's all I can say is it would be nice to jump into a F4u-1C once in a while. If it was historical matchups and I was flying against all Jap planes, I would actually choose a cannon armed version, whether it be -1A,-1D, or -4. I would take larger ammo load over 20mm cause I know I knock down a Jap plane with a burst or two.
