Gray Area Strikes

[btdt]

Have been contemplating the gray area for 2009.
At lower levels of baseball I call every strike I can resonably get.
As the talent level moves up, my strike zone tightens up.

Pitch low in the strike zone that could be called either way. (Gray Area)
You want to be consistant so would you lean toward strikes or balls and why.

High in the strike zone?
Inside/Outside??

Before someone claims the strike zone is the strike zone, umpires are human and you have to decide what you just observed and your decision will be inaccurate at times.
