I agree with the slow down philosophy.
It is much more important to be right than to be fast.
I have had my embarassing moments when I called a quick out on a tag at 2nd base, only to see the ball trickle away from the bag after the dust has cleared. Or call a catch of a fly ball only to see it drop to the ground because Willie Mays didn't hold on to it.
Slow and precise will invariably help you to make the right calls on the bang bang plays as well.
