Try to stay above them, but don't always all out climb as they do have a better climbrate, if you do get one on your 6, use your superior roll rate and dive speed to get away. Other than that, get a wingman or two to really f*** their day up

Yip, much better tactic than trying to get them to slow down and stall. I prefer to fly the Mig, if a Sabre slows down he's screwed, Mig just has to open the throttle and he can accelerate and climb much quicker than you.

Sabre's main advantages are: higher top speed, roll rate, G-suit, fast rate of fire.
Mig's main advantages: Fast acceleration and climb, powerful armament (accurate even at long range), higher operational alt.

Don't slow down
Don't fly in a straight line (he'll knock you down from 4 - 500 metres)
If you're close to blacking out in a turn, he's probably already asleep
Don't get suckered in to a turn fight, he'll retain and regain energy better than you
Have a wingman handy
