Height vs depth: how to master trajectory control
Playing with margin without losing ball weight is a trainable skill once you understand the right balance.
There is a common idea that if you play high you stay short, and that if you want depth you must hit flat. In practice, real control appears when you combine height, speed and spin in the same trajectory.
NetLiner helps because it makes that balance visible. First it forces you to clear a higher window and, after that, to adjust the ball's descent and depth with timing and rotation, not with rushed shots.
With training, the ball starts travelling with more weight and tactical direction, which lets you push the opponent back without living in permanent risk.
Takeaway: mastering trajectory is not choosing between safety or aggression, it is knowing how to blend both with judgement.
