Why do we say this? a 36.5" stick forces you to be lower to the ground which gives you more control over the ball and a better view of your surrounding area. While in a defensive player the 37.5" stick gives the players that extra reach. We can recommend a stick length based on your height or playing style but it comes down to your preference in the end.
Note: the above sizing is only an approxomate guide to help you best purchase.
