I've been playing the London System as White for over twenty years. My current USCF rating is 1804. My peak published rating was 2002.
You can play the following moves against almost any Black defnese:
5 Bd3 (or Be2)
Sometimes you'll have to play h3 to give the bishop a flight square on h2.
Hope that helps you with the White pieces.
As for Black (ugh!). I've been playing chess for almost forty years and I still don't have a clue as to how to play Black. I've tried everything without noteable success. Good luck!
