Softer sponge offers more control, slightly less speed than regular H3 Neo. Works great on fast blades. Mushy feel on soft blades. For fast attack and looping close/mid distance from table. Provides chops close to table with great spin. Outstanding on BTY T.B. Spirit or Viscaria blades or composite blades that are rated OFF or OFF+. Ok on 7 ply wood blades with large sweet spot. Some advanced players who play away from table may find it a bit slow. Tacky topsheet with orange 37deg sponge. A very nice playing Chinese rubber.
