The fact that the tater is one-shot lethal and that the 109K is both fast enough and maneuverable enough to saddle up right on alot of airplane's tailpipes (The omnipresent P-51s for instance) makes up for the ballistics deficiencies.
Well not only are the ballistics marginal, but so are the bullet spread and ammo load on the tater. It's the combination of these three traits which makes it a difficult gun to learn - long time of flight/low muzzle velocity, low ammo load/firing time, and dispersion pattern.
It's definitely not my first choice among the available 109 guns packages. I think you even mentioned you prefer the 152 because it's almost 50% extra ammo on the tater - the extra rounds make a huge difference because one is less afraid to take longer snapshots for fear of wasting the precious few available taters.
I'm not really arguing about the ENY (hey, I thought it was at 15), but the 109K does have its deficiencies. Fortunately they suit my flying/fighting style and don't detract from it much.
