I think as a natural lifter training for example in a push/pull or push/pull/legs split it doesn't make much sense to train the front delts isolated. These are already trained during all push exercises like flat bench, incline, decline bench presses. In addition, a very pronounced front delt also ensures that some people get problems e.g. during chest exercises to feel their chest properly because their front delt is too dominant and helps to lift the weight.
I’m not ulisses but if your looking for strength and long term mass go heavier and lower rep but if your looking for adding lean mass to your shoulders work around 12 reps unless supersetting or trisetting like ulisses was doing
