    The pimple structure of t64 is different
    longer distance etc
    https://www.google.com/amp/s/ttgearl...n-rubbers/amp/
    This is not big deal
    table tennis market is full of copy products.
    the difference is material and quality of sponge or topsheet

    2. Butterfly says the T19 pimples ares small but packed closer together. If so many thinner pimples will not bend any more than wider more widely spaced pimple.
    There are some inconsistencies in Butterfly's claims, yes. But are you telling us that size, shape and density don't matter and don't make a difference in anything and in this case in rubbers? Only the sponge makes a rubber faster? Those also seem like inconsistencies.

    T64 does not have thinner pimples than T05 and T80, they're all 1.7mm (vs. T19's 1.5mm), and T64's are more spaced out/less dense than on any other Tenergy rubbers. T19 is something new, the difference to you is probably marginal. To me, it's about feel more than it is about said performance.

    I agree that speed is relative, yes. It does matter on what kind of shots you judge it by too.

    To me, T05's topsheet feels the hardest, and I find it to be the outward fastest of the Tenergy's especially for topspins, whereas Butterfly says T64 is the fastest overall...

    I do however think that T64 is fastest in blocks and smashes, perhaps drives too.

    And T05 is definitely the spinniest, but T64 is easier to generate spin with due to its softer nature and it's more controllable.

    Given the T19 and T05 weigh the same, the difference between them comes down to how that same mass is distributed. Butterfly is basically playing with the shape factor of the pips here. The slenderer pips of T19 should have a smaller shape factor than those of T05, which would make them easier to compress/bend and softer to the touch. The more packed pips of T19 also translates to more of those slenderer pips per given area for the applied force to be stored as elastic potential energy and to be returned to the ball, which is supported by the limited data Butterfly provided.

    Before anyone asks, T64 has taller but less packed pips, and with less of those taller pips per given area, the topsheet should bite into the sponge more for the same amount of force, giving more access to speed. Another factor not mentioned often is that the rubber formula could be different, which could nullify and overcome the effect of pips as shown by the limited data Butterfly provided. Same logic for T25 and T80.
