Dynamic work, for powerlifting, is meant to improve speed on the powerlifts and also perfect technique. If you have a max effort day and are following the conjugate sequence system, then you are rarely ever doing a squat, bench, or deadlift.
On the other hand, jumping and throwing are speed-strength work in its truest sense. So, do both. Do the jumps and throws first, then go onto the dynamic squats, deads, and benches. I used to do weighted Kneeling Jumps after speed work and got very very fast off the floor with my deadlifts.
