hey guys, im lookin to switch up my shoulders and lats routine with some new workouts. any suggestions?

Lats:
weighted pullups
Old school t-bar rows
barbell bent over rows
Lat Pulldown
1 arm bent over DB row
Shoulders:
upright rows
Mil press
DB press
Lateral raises
arnold press
Just try variations.
Try heavy Yates rows for your lats. You can pull a lot more weight than you could in a strict form barbell row, and it makes your lower lats feel like they're on fire.
Also try Kroc rows if you never have, grab the heaviest dumbbell in the gym and try and set a new rep PR with it every week or so.
I like front DB raises, wide grip upright rows (just started doing to put more stress on outer delts), and cable lateral raises
