Staggered Sets vs Circuit for Rhomboids, Traps, Rear Delts

Hi,
On the high performance program staggered sets of traps, rhomboidal and rear delta, I’ve found this doesn’t work well with me, rather I like to concentrate on density and getting through each exercise as quickly as possible using optimal performance… in your video you mentioned you can do at the end of the session 1 circuit style of 3-4 exercises to target these muscle… How does this look as an example? (Reps how many circuits, to failure)

Thank you
Henri
