I know some will not receive this well, but....the strike zone is the strike zone and should be called as the strike zone.
The fact that NCAA, NFHS, ASA, USSSA, NSA, ISA, ISC, AFA, M-O-U-S-E!!! all give clinics which tell the umpire how they want the strike zone to be interpreted which, in some cases, does nothing more than cloud the issue, not only among the coaches, but the umpires! And the bad part is one year it is a car logo, the next a balloon and I wouldn't doubt we see a zepellin above the plate in the near future.
However you choose to call it, just don't move it around. Keep it simple and consistant.
JMHO,
Mike
