The best stick handlers and play makers generally use relatively short sticks. It all boils down to how the length affects the top hand.
A longer stick forces you to hold the top hand up forcing the elbow out and away from the body. (Good for Goons)
A shorter stick allows the elbow to remain closer to the body it also reduces the space between the hands.
This for me is very close to the default for puck handling and when shooting it's far easier/quicker to release a puck from that position..
Try dragging a puck to change the angle with a long stick and see where that elbow ends up before your release it's feels completely unnatural.
Using a shorter stick two things immediately happen one the release is far quicker two more wrist flexibility/maneuverability generates more power.
My ole man forced me to use a stick cut just below my nose which put it about chin level on skates.
As I got older I thought I was wiser and deviated from this and it affected my play without me realizing it.
I broke my lumber during a game and borrowed a smaller stick my game suddenly took flight to the levels it should have been at.
That is when I realized what was going on. That broken stick put some hardware in my trophy case.
Try it at home kids you'll see what I mean.
