Interesting how much he emphasizes the 'through' component on FH. I guess the conventional teaching must have been really ingrained in him.
He also emphasizes 'through' component on serves and I have to agree. People are so focused about the spin on their serves they tend to forget the importance of the 'through' component. He mentions even on 2nd serves the 'through' component should be the major focus.
