Since the original thread has gone into remodelling my forehand:
I decided to start a new thread about my serve. After 20 years...I can serve, but there's some weird hitch in the kinetic chain. What I can see is that the right hip/leg comes forward. As always, comments and suggestions are most welcome.

It's pretty much good for starting the point, not much more. No pop.
Please do help me fix it
