Campagnolo 11-speed shifter/derailleur compatibility chart

I'm actually curious to know if the Potenza FD and Chorus 2015 FD are the same geometry and shape-wise, just different materials?

I chose the Chorus one for my Potenza build because it's black (the Potenza has a silver cage).

I seem to be constantly throwing chains off the inner ring no matter what I do with the setup.
