Leviathn.. it is all well and good to make fun of Lazer, but I think he has a point. He probably *could* double or triple is K/D (and improve on everything else) if he were to fly a N1K, Spit or La7.
Actually I think for him it'd be the Spit9 or N1K2, since those do everything better than the P38 does. I think if someone has a K/D of X flying the P38, it wouldn't be at all unreasonable for them to have a K/D of 2 or 3X in a N1K or Spit.
Same for the la7, if you are a 109 or 190 pilot with a K/D of X, you could reasonaby expect to double or triple that in the La7, along with improving K/T and such. Why? Because the plane is simply better.
Course, thats just my 2 cents.
