How does the flex of a hockey stick affect your slap shot?

Answer 1

its allows your stick to bend more when taking a slapshot thus creating a stronger spring motion which shoots it faster then a higher flex stick. better for defensmen is lower flex(not to low or you will brake it.

Answer 2

Very much so....it spins the puck more, which means the shot will be hard and fast. Defense players tend to use flatter sticks though
