Kai has packed more muscle on his body frame than Ron at his scale.
Kai has a completely different structure. He has bigger joints than Ronnie did
and Ronnie's detail is on another level than Kai's.
There's a reason Peter McGough said Ronnie was a walking anatomy chart this
year I'm posting from.
The side chest might be off a little on the scale but on the most muscular the arms
are almost the same size and Kai's head appears a tad bigger.
Anyway, not perfect scale but you get the point here.
