If you train for Distance I would not consider Direction.
In the beginning, it is only about clubhead speed. Distance comes in combination with all three factors.
A functional grip is important to create maximum clubhead speed!
Second factor you have to minimise spin in order to hit long Drives. You achieve this by hitting with an upwards motion at the ball which reduces Spin.
Reduced Spin gives you maximum distance
In order to maximize distance, the last part is to optimize center strikes. The more you hit the middle of the club, the more energy is transferred into the ball.
