QFE.
Yeah that's a good approach.
The delts have always been a bit of a conundrum to me.
The front delt pushes, the side delt lifts your arm laterally, and the rear delt is a pulling muscle. So I do front delts with chest, side and rear delts in my back workout.
and then occasionally I'll leave em out and hit them all after a days rest, just to keep 'em honest.
