Using left hand for some mechanics

[SAump]

I would bet there are many umpires who appeal check swings with their right hand. I disagree with the given rational behind left handed checkswing appeals, but I will not be picking NITS again on this thread. Despite my reservations, I can adopt the "correct" mechanic simply to please the bosses. The left handed check swing mechanic is now gaining universal appeal. I learned about it by reading this website. I would still prefer PU point at the batter with his fully extended left arm and then ask BU, "Did HE go?" That seems to be the only realistic provision for this mechanic.
