Butterfly Dignics 64 Rubber
High performance rubber Rozena, pursuing "tolerance"
In the highly technical world of table tennis equipment, Butterfly strives to give our customers as much information as possible to help each person choose the equipment that best meets their needs. To that end, we are now publishing a list of Sponge Density Ratings. In general, the higher the number the denser (harder) the sponge. Players who swing harder prefer the harder sponges. The denser sponges have more stored energy but also require more racket speed to compress the sponge and release this energy. The all-round player or players with shorter strokes will prefer sponges with medium or softer sponges.
