DESTO F1-HS: Feels not harder, but is significantly faster
Almost all top professionals prefer to play with harder rubber. They then use many layers of speed glue to bring the rubber up to full speed and maximum performance. With DONIC DESTO F1-HS, we have adopted a similar principle: we have incorporated a maximum speed-glue effect into a sponge with 50 degree hardness. The built-in speed-glue effect neutralizes the hardness, giving it a softer feel and thereby increasing ball control.
Even though we have increased DESTO F1-HS’s speed, it is very spinny and feels like it has a medium-hard sponge rather than a hard sponge!
