C3 vs C4 in London System

Avatar of ZedsDead87

I've been playing a lot of queens gambit and feel comfortable playing the c4 move. I also like to play the London set up when applicable. My question is when would one push C4 vs the typical C3. I don't want to develop like a robot but I'm struggling on when to play C4 vs C3. I guess my goal is a blend of London and queens gambit. Maybe even queens gambit then exchange against Slav n declined and then morph into London.
