Your approach is 8'3 1/2
Great dedication at camp. Focus on starting with your feet balanced right foot slightly in front of left. Work hard at taking your left right left and getting your left shoulder parallel to the net. You have a nice swing and follow through I would like to see you work hard at driving your arms before you hit the ball. And have your hips face where the ball lands. Once you stay open to the ball and have your footwork down your timing will become much easier. Stay dedicated I have no doubt you will get this. Keep it up!
