    If you don't have a ratings system already then I would use ratings central.

    That is much different from how much spin a ball can accept. Have you ever seen a ball with a spin limit?

    My why question was asking you to justify your statement about DHS ball stretching the...
  3. How much longer? Igor didn't mention how long....

    How much longer? Igor didn't mention how long. Spin a ball on a table. It will spin for a very long time and that is with the friction of the table to slow it down. The time the ball will spin is...

    There are too many distractions. TV and video games for one. People are "busier" now. In my case the club is 1 hr away or more depending on the traffic. Traffic is awful now. It wasn't that bad...

    No one noticed that according the math and physics, the thicker shell ball will have a lower inertia than a thin shell ball. This means the thicker shell ball should be easier to spin. This...
  6. Then you calculate. ...

    Then you calculate.


    I=(2/5)*mass*((R^5-r^5)/(R^3-r^3))

    R is the outer radius of the ball. r is the inner radius of the hollow sphere. R-r is the thickness of the shell.
    The inertia I get...
  7. Langel is correct! The ball with the thinner...

    Langel is correct! The ball with the thinner shell has more rotational, we are talking about spin here, inertia than a thicker shell ball. This is because more of the mass is farther away from the...
  8. They will if the radius of the balls is smaller. ...

    They will if the radius of the balls is smaller. They will also rotate faster if the inertia of the thin shell balls is less.
    This assumes they are subject to the same stroke.
    The question is how...

    That is a cheap shot. Why don't you state what isn't true? Can you?

    I really don't see the what the argument is about. Any ball with top spin is a top spin ball. A loop kill is a subset of top...

    What do you mean by even?


    that is the easiest way as long as your stroke is upwards and not forwards. Obviously if the ball is high you can just smash it.


    This is wrong, wrong, wrong. ...

    Yes, this was taken out of context. I was responding to someone talking about hitting through the rubber and the blade. Not, hitting through the ball but now we can see that 'hit through' has no...

    You quote without context but you are right. Hit through what or where? It is sloppy. The stroke must apply force upwards and eccentric. That is a good description of what must be done. I know...

    Going for a loop kill against a very spinny back spin is very difficult because you can't hit through the ball like you normally would. You need to bring the paddle back down behind your knee and...

    That testing doesn't look like a TT rubber was involved. It is best to have hard but frictionless material in the chain ways of conveyor lines. It reduced energy costs and wear.
