The Butterfly Rozena is faster and creates more spin than both the Roundell and Spin Art, which are comparable pimple-in rubbers. Though the Butterfly Rozena is slightly slower than the Tenergy 64 it does create more spin than the Tenergy 64. In contrast, the Butterfly Rozena creates slightly less spin than the Tenergy 05 but is faster. The Butterfly Rozena is also easier to use and more forgiving than either of the Tenergy 05 or Tenergy 64 rubbers.
