That's a pretty smart/slick layout. i do something nearly exactly like that, i like db's for rear delts however because my traps need more work anyway. i vary the rom and movement of my bent over raises floating in and out of a row variant and a rear raise, the theory/idea is to essentially crop dust the entire upper rear area. finding the groove w/in the rom for rear delts is key, then blast away w/in that perfect zone.
i might add an extra horizontal movement as well because i generally save rack pulls for a different bonus day depending upon the cadence of my week, if i'm ahead or behind on my rotation of shit.
if i'm not 100% pleased w/ the degree to which i smoked my rear delts i hit them again w/ more isolated movements on delt day, if they're good...i allow my delt day focus to be on oh presses and side raises. front delt iso work is gauged on how my chest day went or what my plan is for chest on the upcoming week.
i wrote too much shit here, sometimes i'm explaining shit to myself just to gain better self insight.
