The much awaited Tenergy 05 FX is finally here, and first reports sound very promising. It’s not yet available in all countries and all retailer, but this is only a matter of time.
You can find some early detailed reviews and pictures on this rubber here: Butterfly Tenergy 05 FX Review
It appears to be a more controlled version of the regular Tenergy 05, and therefore suitable to a wider range of players, particularly lower level player, who struggled to control the Tenergy 05.
Basically the Tenergy 05 FX is a Tenergy 05 topsheet with a softer but similar sponge. It retains most of the benefits of the regular 05, but it’s more forgiving and easier to play with.
