I used to fly the Ki84 almost exclusively.  Great plane!  (Tyrannis, you need to learn to respect the Ki!)
But this tour I have decided to learn the 109K4.  Most of my sorties are in it.  That said, I have flown some of the other 109 variants this tour and have been reminded of how much I love the 109F.  I would fly the 109F all the time, but in the MA there are too many other toads chasing my quarry and I seem to get mostly assists.,
I like the 109F model so much I have even tried flying in Midwar, only to find that most people don't want to fight there.  In fact, most Midwar players are fully involved in trying to "sneak" a base capture.  If you show up in the sector they are in, they quickly bug out and seek a new base to "sneak".  Sad, so sad.
