I've found myself evading while looking solely in dead six view more in the 190 than in any other plane. Your defensive manuevers in the 190 will rely on your quick recognition of what the enemy will do, since almost any shot he tries to line up can be thwarted by virtue of your superior roll rate. 190 evasives are a little different than maybe what you are used to, since it's neither a "yank the stick and induce luftberry" or "drop flaps/kick rudder and force overshoot" type of plane. What you need to be doing is using your roll rate to offset flight path trajectories between you and your opponent.
For example, you're in a mid-high speed scissors with a bandit 400 yards back to your six and constant. You can see that he has been pulling his nose slightly ahead to get shots on your scissor breaks. To get that lead, he has to watch the roll of your wings and start rolling that direction as soon as you do. So try this: rather than predictable right/left/right breaking during scissors, why not start a sudden left break by rolling 270 degrees to the right. Your bandit will see your initial roll right, and can either
a) assume you are breaking right, pull some G's for a lead shot
b) follow your roll for it's completion
In case a, you are already breaking in the complete opposite direction by the time he realizes you're not actually under his nose, and in case b, you will complete your roll much faster and be on your new heading much quicker than the bandit can match.
