to choose based on your position, age, and style of play. Shin guards should cover most of the area from your ankle to your knee. Measure your shin from just below where the knee bends to about 1 inch above your shoe top. This is the proper length of your shin guard.

an airsoft gun can break skin at 300 fps it all depends on what weight bbs you use like .2, .25, .3 ect. it also depends on how far you are from the person when you shoot them. it all depends. i was hit from a 300 fps gun and the bb popped my skin open and ive been hit by a 590 fps gun and it didnt leave a mark. im also on an airsoft team with people that have alot of experience.
A pitch shot is hit high into the air. A well-struck pitch shot will land within 20 feet of the pin and then stop or roll backwards, since the grooves on a wedge put backspin on the ball. Pitch shots can be executed anywhere from just off the green to a distance of 120 yards.
