tenergy 64 is really fast with hard sponge . xiom omega iv elite is slower with softer sponge . xiom omega iv asia with the hardest sponge of all omega iv series is the closest one to tenergy 64
hard sponge = big swing = maximum speed (hard sponges need more power to compress but when they do they give more speed than softer sponges , it is like the modulus of elasticity in springs)
soft sponge = big swing = maximum control
tenergy 05 and xiom omega iv elite have soft sponges so they are similar
My experience is the opposite frenzy. 05 has harder sponge and is preferred by top players as a forehand rubber. 64 is softer, has a higher throw and is more common on the backhand (as mechanics and technique is generally worse on most backhands IMO).
Thank you all. I send an e mail and asked the xiom.
The answer was that the omega pro is close to tenergy 05.
obviously el gato wants a rubber cheaper than tenergy with "similar" efficiency or at least close to tenergy
