Zaphod...
Hang in there buddy. I had a hard time for same reason you did. The best thing to do, I found, is lighten up on your AH time, only hit it sporadically, and not like you used too. This "time" allows for an adjustment, and you can enjoy the benefits of Tir vector breifly, without getting so frustrated you want to switch back to hat views to get some kills

Now I couldnt think of using hat views, flying is MUCH more natural, the only part thats hard is gunnery... and well... thats always been hard.
What I found interesting was taht with hat views "set", I had actually learned to fly the airplane well in any one view, because I "knew" the angle I was looking out of the cockpit.. now with that angle changing, I had to "relearn" to fly the airplane into the views instead of "from " them.
(disclaimer... half a bottle of cabernet down my hole if this doesnt make any sense).
