Take the Pony up with 50% fuel, and two drop tanks.
On takeoff, drop one of the tanks, and use the other to climb to altitude and then to get to combat.
After that 50% will be PLENTY to fight with and rtb, but you will still have decent performance. Just be careful the first couple of minutes of combat as you will still be pretty heavy.
Try it, it works
