Flicking a ball well is an attribute that you need in all positions, here I am shooting at Goal.
Ball always starts in front
Have your stick just being able to touch the ball
Hands apart, and potentially bring the lower hand up the stick a couple of inches
Drop your weight down
Stick slides in, and as soon as it connects - you deliver the power
Left hand temporarily into right forearm
Try to whip through the ball at the end to generate maximum power
Adjust your feet slightly squarer to flick to the right
Try not to make too much noise upon connection
Happy flicking people.
