jmccaul-
I do not by any means think the spit is an "uber-plane"... competent 51, 109, N1K2 and La5N pilots will give a spit fits when flown properly. I'm flying the La5N almost exclusively, and don't find the spits any more difficult than anything else.
Furthermore, AH cannot deliver a/c that didn't exist; the Spit was a TnB plane with few peers. What plane do you feel we need? No sarcasm intended, an open mind here...
