For the Aerial Threat trait, if your player is 6’2 and under, they should aim for Heading 90 and then get Strength or Jumping to 85. For players ranging between 6’3 and 6’4 they should aim for Heading 90, with Heading 75 for 6’5 and over. The Aerial Threat addition will be dominant in the air and win the headers over anyone else on the pitch.
