i'm using a Dawei 2008 rubber that is about 1 years old but still seems to be well. But sometimes when im top spinning the ball goes out of the table even with a good contact and closed angle. So if you are looping fast with a old rubber which in my case is the 2008 xp can it effect your loopkills to the point of going out from low amount of topspin or is it my technique.
