Butterfly Sriver EL

Butterfly Sriver EL combines Srivers's top sheet with a medium-soft elastic sponge. Do you prefer a hard or soft sponge? If you like a hard sponge, then you can choose the normal Sriver. If you prefer a soft one, then Sriver-FX is ideal for your play. But, if your requirement is in between the two (and this is where most of the top players are placed) then Butterfly recommends the Sriver-EL.
