I agree there are associated dangers involved here, especially if there are beams etc... However in the cage I use, there aren't beams or weird lighting to contend with. Yes sometimes on a ball popped up off the bat, the ball will bounce downward at a weird angle. But those are far and few between. As long as your tunnel is 10' tall or higher with a fair amount of sag (not stretched super tight) and at least 50' long, you can play cageball. Its by far the best practice possible in these scenarios.
