Making a shooting range in my yard. Need a small floor material that's as slick as possible for rubber pucks.?

if you really want to improve your shot you have to simulate it as close to real as possible.......put your skates on with skate guards...now shoot the puck...it is to obtain balance ......also shoot of the front foot and the back foot....this will enable you to shoot when you are in full stride....any clean surface will work....do not worry about the drag because it always better to have it harder in practice than a game.....repetition s your greatest et....see you in the NHL
