re: Help me optimize my split please.

hypertrophy wise, assuming aethetics is goal, so mainly upper body would be better like you have it

i would focus it somewhat like this

push- chest & tri focus, shoulder secondary
pull- horizontal and bicep focus. DL variation
legs- squat, 1 unilateral and calf focus
push- shoulder and tri focus, chest secondary
push- deadlift and vertical pull/bicep focus

or something similar. just focus on getting really strong in incline db bench, weighted dips, close grip bench, weighted chins, chest supported rows, squats and sitting DB press and you wont have to worry about order and all the other BS. just focus on adding strength.
