The reinforced ball felt is more so that it can withstand the heavier blows the ball faces in the hard court. The conventional ball felt has a firmer texture and is designed for use in red clay and indoor carpet courts. If a reinforced ball is used in the oil field, the thicker felt will absorb the dust on the gravel of the court and make the ball “heavier”, which means it will become more in the game than the conventional ball. Slower and lose flexibility earlier. Conversely, if you use a regular ball on a hard court, it won’t be too fast because it doesn’t have too much felt to “bite” the ground. At the same time, the conventional ball is not designed for the large wear of the hard court, so if you use the regular ball in the hard court, the ball will soon be “bare” and unbearable.
