Any seoi nage experts here?

Hey I'm looking for anyone who has morote seoi nage as one of their tokui waza to give some tips and learnings they found the most helpful for getting their seoi nage to be effective. I find there's a variety of conflicting advice out there on instructionals in regards to leg position, lapel position, wrist action, head position, and foot work, so I just want to hear from those who have studied this throw extensively. Thanks! My stats are 5'8 150 lbs
