I'd be interested to know what indie shows Cwalker has watched recently as well. Or is it just to the clips that people pull to make a point that you're going off of? Hell, either way, I'm right there with you on wanting much fewer superkicks in wrestling.
As far as the rule, I guess my first response is just lol, but honestly I think the slapping sound has definitely lost all significance so if this means that you don't see it on an every match basis, it might be more important when they pull it out to really try and convey a kick as extra devastating. That's the hope at least.
