It comes down to what is actually working for you, not what someone else endorses. Platz stood out because of his high volume for legs....which should tell you something since many others didn't take the same approach.
It worked for him....almost to his own detriment.
My shoulders are what most comment on and I do not use high reps. I do go fairly heavy....doing more weight than most on side laterals...and it shows.
I don't see anyone who can side raise more than 60lbs with 'decent' form who has small delts.
Get stronger and train them often. That is what will make them pop out.
