Platz IS the king and always will be one of the best.
Personally I have tried many different methods over the years and for ME and due to may injuries (motorcycle accidents, smarting off to my wife, and other mishaps) I can't lift heavy like I used too so I have changed my complete workout to lighter weight to high reps and I have not seen this much muscle size increase in over 10 years. My joints don't hurt as much and I am getting new growth I hadn't gotten in years going heavy. I use slow high reps and several more sets per body part.
I will admit I am not as strong as I was 10 years ago but that may or may not be age but I am also getting hurt way less.
