Strike Pitch - Do you still call it?

[LakeErieUmp]

BigUmp - yes, there's a bigger strike zone for a 6th grader - but once you determine it stick with it. Don't enlarge it when you need a strike.
Experience brings the place where you can make the call that keeps the batter and pitcher happy. The sense I was getting from the posts was that the zone can move depending on the situation in older levels. Changing Air Trainers to cleats and blue to jerseys with numbers on them, it's players jumping on US for calling outs at first in the seventh that were safe in the second inning.

But like I said, I truly appreciate this back and forth. It helps me.
