I think you should be commended for the block 13 idea. It works well generally and you’re right, there was little atmosphere down that end before. But I respectfully disagree with you that the megaphone works. It doesn’t - at all. In my opinion (and I’m not alone), it kills the atmosphere. It‘s just terrible. No problem at all with the other stuff though.
The way the entire blocks evolved over the years has great points as well as some bad points and I can agree with you that there has been a couple of times when the megaphone hasn't been used properly and it's sounded dog awful but I'll always give them the benefit of the doubt, they'll evolve it and get something worked out
