Causing axis tilt
Axis tilt can be a useful tool or a detriment to your game, depending on what you do with it. If you keep your wrist straight forward,
then tilt is minimal and you'll track closer to the thumb and fingers. If you tilt the hand to the inside, the track drops and your ball
is more of a spinner and reacts later and with less force. Might help sometimes on drier conditions. Just another trick for your bag.
