Is dumbbell incline bench necessary for upper chest

[FourOneDeuxFitt]

for whatever reason, I remember reading this..
Decline bench press better for pecs than incline bench press

I can feel the upper chest with dips, depending on how the movement is done.
my old mantra, besides "be the run" when I was running a lot was,.. "chins and dips, chins and dips". all day.

I just read this. Actually very interesting.
