That made me laugh out loud just imagining him scaring himself with his bark.
That's interesting about the larger breeds needing to wait longer before being neutered. I wasn't familiar with those studies. If you have references for them on hand, I'd like to see them. Thinking about it, it makes sense, since they probably have a longer growth period than a smaller dog and more demands on their skeleton. Of course, if you wait that long to neuter them, it would be purely for birth control and not for preventing any of the bad habits male dogs get when they hit puppy puberty. But, as you said, play it by ear...if some of the bad behaviors start to show up, you can decide then to do it sooner. It's a good indicator if all the males that breeder has are well-behaved.
