I hated it back when Atlanta Braves had Smoltz and Maddux and they'd get the calls and the other teams wouldn't. Call it the way the original rules say, and use the new fangled computer system to give the umps a post game grade. It would be nice if there was someway to keep them honest. A frustrating weakness of the sport for a century and now they have the technology to do something about it. How often have you seen a batter take a 3-2 pitch, throw his bat and start trotting to first, and then the ump rings 'em up on their 3rd strike, just to demand respect.
I ain't saying I could do a great job of it, but for those that do, grade them to keep them on the up and up. My .02
