Butterfly XS
Butterfly XB
Take a look at atttachment at the bottom pulled from above pages
The spong hardness for both is 30 . Does it make sense ?
Both speed & spin for XS are higher than XB
Again does it make sense ? I would expect the Spin version (XS) to have more spin but less speed & Nlock version (XB) to have more speed but less spin . I understand arc for XS being higher than XB
So I would tend to think the sponge hardness value is stated wrong. XB should be higher than XS ??
Unless only the top sheet for XB is harder than XS ??
