I wish there was a decent wall to hit off of around here. The one at the local park is plastic and slightly wavy/uneven. The plastic just doesn't send the ball back at a decent height/trajectory. I'm a fairly hard hitter and the ball comes off the wall so fast I wind up hitting weird out of position shots rather than being able to setup, yet if I don't swing as hard, the ball won't make it anywhere near me off one bounce. Such a bummer since I'd really love to have a good wall workout.
