If people want to fly spit 16s, by all means fly spit 16s. To me, there is zero challenge in that bird, and I only up it from HEAVILY capped fields. Now the HOing and hording XVI's I could do without...but that's the pilot not the plane.
Side note: It really bothers me when people make the "oh its the history that I love!" argument for the Spit XVI. This bird was deployed en masse only after the allies had almost full aerial superiority over Europe, at least within the areas where the Spitty could reach with it's wee little midget legs. Additionally, the war was at that point HEAVILY in favor of the allies, especially on the Eastern Front. Finally there's the fact that most of Germany's best pilots were dead or captured. Therefore, the XVI did a fair amount of ground pounding because of this superiority and lack of range. How many of you use it as an attack/fighter the majority of the time in game?
You want a good historical Spit that was important to the war effort, take the I or V.
