aircraft polish is only useful in planes that use dive speed as a form of evasion. XF-90 and F7U come to mind.
Your weak points in an F86A are its guns and its wide cone of fire despite being cowling-mounted.
Its upsides are speed and manuevarability.
You want to maximize its strengths while minimizing it's weaknesses.
pilots should go Engine Guru I, Marksman 1, Aerodynamics Expert, Aerobatics Expert. This uses your first 8 points, and helps with the weakest parts of your plane while improving the best. Your next 6 points can be distributed based on your personal preferences, but I would personally go for Evasive Target followed by resilience or Marksman 2.. Cruise Flight helps with initial climb and regaining altitude after a fight - not something an F86A will ever have an issue with.
To assist with the relative weakness of your plane inability to take fire, I run Improved covering. This is more for the reduced crit chance than the added HP. To boost it's speed, Engine tuning, which then also gives an extra 2% to engine power from Aerodynamics Expert - same benefit at Engine Guru 2 but costs one less point. Lastly, I take improved radio sight to make the cone of fire much tighter which helps with your ability to quickly take planes down, and greatly helps when you are hitting someone near the end of your .50 cals range.
Running a lightweight airframe will only help you in a fight against another F86A, but in reality whoever gets behind the other first wins. The F86a will not get out turned by anything because it isn't running the LWA, or be able to out turn something because it is. Where you will see gains running this is turning back onto a heavy fighter which is what you were made to take down. With proper positioning as you dodge, the benefit is minimal.
