I presently have an 8 footer with drop pockets. My daughter and grandaughter moved in with me and its become too big for my place. I was looking at getting a 7' valley barbox for house. What's the best way to dampen down the noise the balls make when they travel inside the table? putting felt on the paths? I figured since I'm in 3/4 leagues and almost always play on valley barboxes then might as well do my practicing on one also. thanks much !
