hi everyone. i was having serious bounce back issue with my simulator so after reading some post i installed some big blue moving covers in back of my screen. it work perfectly and reduced bounce back to 3-4 feet max. the problem is after just a few rounds the blue cover is getting destroyed by the balls. i lifted the white screen and looked at the blue cover and it must of had 100 holes in it and now its barely hold up. still works to reduce bounce back but i am sure will fall down any round now. anyone have another recommendation or as seen this. what material would resit better . this was a heavy material so i am surprised it did not hold up much
