Ok, my quick take on this.
High speed rolling Scissors?
If you are low, and an La is on your 6, odds are you are not at high speed.
Thus you will be forced into a low speed maneuvering situation,and likely shot down soon.
The 190 has to be used as B&Z against ground targets, and air. Never turn unless you know your clear of threats.
When reading things about any of these aircraft from history books, you got to remember the History books were written on the original scenarios.
Late war engagements, had lesser trained pilots in the La's than the 190's, and it weighed on the outcomes and tactics, for the most part.
Not true in this Simulation we now play.
You are flying against people with thousands of hours at the stick, and some of them fly only one aircraft for the most part.
You can't expect to pull a particular move over, and over, and expect to win against a good pilot in a more maneuverable plane, at an altitude that they have most of the advantages, due to there aircraft.
The only answer is, no matter the difficulty of achieving is.
Wingmanship, and fly your ride to it's strengths. (B&Z)
