The mass monsters carry significantly more muscle tissue, but smaller guys can get really diced and the muscle quality shows way more for some reason. Why? You see natural competitors completely sliced, although they are small as hell, like 150 lbs, they look like they are much lower bodyfat than most IFBB Pro's, even though they carry less muscle tissue. Even though Phil Heath steps on stage at probably 5% bodyfat, he looks like he's 10% bodyfat, and the natural diced competitor steps on stage at 5% bodyfat and actually looks it, dry to the bone, striations everywhere, even though he has 100 lbs less muscle on him
