Wow... a lot of filtration for a 120l! I have 1 in and one out at each end with my Eheim Pro2 and Eheim Pro3e. I considered both intakes in the center and outlets either side but my tank top (inbuilt with glass sliders) won't allow this.
Really id say its up to you... i mean they are still going to be both filtering out ammonia.
