-1 is my opinion
But till you get your wish (if you ever do) either don't chase them, climb higher than them so you can catch them, or fly something as fast, or faster than them....
I too hate run-90's and pee-51's because they use their speed to run all the time, but the cool thing is it's the only thing in their bag of tricks. When you catch one, it's often easy to kill them because they have spent so much time running, they don't know how to fight. 99% of Puny drivers (sorry, Pony drivers), couldn't buy a reverse, much less execute one.
Suggestion, fly a P-47M. It's almost as fast as the speed demons, dives better, and I love the dive flaps. I can't tell you how many 51's I have gotten to auger behind me because they were silly enough to follow me into compression.
It's also fun to show up with a little more alt than them. Pretty much every pony I see hits the deck after seeing anything co-E.
