Want to maximize chest recruitment? Do 5-angle flyes.
Various angles of adduction are necessary to maximally recruit the pecs from the clavicle to the sternum. This exercise will hit most of them to stimulate new growth.
As you fatigue in one position, adjust the angle to a new position: high, mid, low or someone between those angles. You can even go back to a previous angle. This also allows you to extend the time under tension, one of the key components of hypertrophy training.
