Mathematically, Heads and Tails would have a 50/50 chance, thus giving no choice.
But with the appliance of Quantum and Simple Physics to calculate the physical movement of the coin in which cause a flip and turn to land with the fact that the heads side has approximately .6mg more from the neutralized division point than in the tails side, thus applying inertia to the heads side, it can be concluded that air resistance slows every income from the heads side and making it slow to further increase chances of keeping tails up.
So in conclusion, I prefer tails because it is 0.0001834523% more likely than heads :3
