I understand what you're saying needsleep, but I have to disagree. If a 160 lb guy has perfect proportions, I don't give a crap. He still looks like a scrawny 160 lb guy to me. But, if a 260 lb cut guy has lagging rear delts, I don't say "psshhh, what a wuss, look at those disproportionate rear delts."
If people are training hard to get big, they'd be very foolish to focus on such a small thing as"rear delts" or hams." Grow as big as fucking possible, then worry about that sculpting crap. I believe one of the main reasons people have such slow progress in the gym is because they waste their time focusing on specific body parts when their whole body actually sucks.
Grow until you squek through doors, then worry about proportion
