Tenergy 64 (The number is a product of the number of tests that gave rise to this peak structure) is the fastest of the Tenergy and more dynamic in terms than T05. The peaks on the surface of Tenergy 64 are slightly finer than on 05, and are further apart from each other. This makes the surface feel softer and more flexible. Therefore, the Tenergy 64 has a somewhat longer contact time, and this causes the "Spring Sponge" to develop its full potential, and a huge catapult is achieved. For middle distance players whose game is based on topspin.
