Naudet, your point of view is perfectly respetable, but mine is somewhat different.
For me, K/D ratio is secondary while K/T is primary.
And while you can have some success in surprise attacks, our MA configuration will minimize at maximun the chances of being surprised. In my case, less than 25% of the victims are due to surprise. And that 25% is mainly achieved nearby friendly bases where there are no red dots for the con on the map.
IMO, more than 90% of spits I encounter are used in a very poor way. Some people think spits are easy kills and I disagree, their pilots are easy kills whatever they fly. But the plane itself is a formidable opponent. It is the perfect ride for our furballing MA, but, if you want, it is also an impressive B&Zoomer, excelent diving characteristics, one of the best (if not the best) zoom climber, good control at hi speeds, little E loose whatever you do, excelent hi alt performance and the best guns in AH. The top speed will help you to get quicker to the hunting area, but diving, zoom climbing and guns are the factors that will give you the victims in your B&Z moves.
Flying D9, when I see a higher 190, specially a D9, I use to ignore it. When I see a higher spit the reaction is very different.
