What do you think fast to the plate while being in control or Slow and control?
I think fast because then you can build up linear energy that can be applied to the rotational power. Which then in return will make you throw faster.
Granted, that Slow and Control will work it is not the most efficent way to throw with the body because then you will use more arm to get to the power you need instead of more linear momentum into quick rotational power.
