The "torpedo bat" makes so much sense I'm surprised it didn't come along sooner but as a fan of "small ball" and tightly contested pitching duels I'd hate to see it give the offense a further advantage, the game has already devolved into a "homer or strikeout" affair.
It's worth noting, though, that while the Yanks did hit 15 homers in their first 3 games, Judge, their #1 power hitter, accounted for four of them with a standard Louisville Slugger.
