Putting a 55 foot batting cage in my backyard. I also have a black flame pitching machine to use in it. I know live batting practice is better, but getting to old to throw. My big concern is the release point of the machine, it releases the ball at about 24 inches. I would like to get this at a more realistic height. So I am building a platform for it. My question for 10-11 year old kids how high would be an ideal release high. I was thinking 24 inch platform for a 48 inch release point. Is this still to low? Most kids this age are approaching 5 ft tall or so.
