I like the batter's box rule most...there's no need for a 30 second OCD routine for the batter between every pitch (though it'll shave 30 points off Tulo's average). The IBB rule is logical, and often occurs while the inning is already dragging on. 20 second rule is ok if used loosely, i.e. enforced when the pitcher is really dragging things along or stepping off repeatedly. Would be a little surprised if the inning/pitching breaks are ever implemented; heck, I think they're ideal at home for a bathroom/snack break. Not a fan of counting the number of timeouts, at least not an allowance for the entire game. I think there's a good compromise here, i.e. all too often the stalls occur when the catcher calls time, the pitching coach calls time, and then catcher walks halfway to get his word in...all to the same batter. It's got to be closer to one of those per inning, not all of those to one batter.
