I think the op makes a good point. I do know that Reeves always trained shoulders first in his fullbody workouts. The emphasis then was more on developing delts than the chest. Personally - and I accept I won't be in the majority here at all - I think Reeves' high, broad and squarer chest looks better than Arnold's. There are some side shots of Arnold in clothes were his pecs are so droopy it looks like a giant pair of hooters.
