If London and Spanky just have to slow down their style to prevent injury, I'm fine with it. As someone else said, it makes their cool moves seem even more amazing. BUT, and this is a big BUT, if they completely change their style, this isn't good, obviously. From what I gather though, they just don't want them to kill themselves 4 nights a week. They are just protecting thier investments.
The only logic I can see behind not letting Hurricane do the chokeslam is if they don't want him to be as much as a comedy character anymore. I have the feeling that isn't the case though.
