On mass monster judging criteria i think Jay has a better build than Dorian. He has a larger structure, More capped delts, bigger bi's, Feathered quads, bigger legs overall, equal calves, better chest, back is weaker, less condition at best.
On what the judging criteria should be Jay is an abomination but then so was Dorian.
No way in hell should Dorian beat a Flex Wheeler.
Unfortunatley, youre judging based on how you judge things, not how its actually judged.
You dont pick out bodyparts and compare them.
You take the entire mandatory pose, and judge balance and proportion, muscular bulk, and conditioning. Those are the primary things judged.
Dorian flat out has better balance, better proportion and better conditioning than Jay, even though Jay out masses him, Jay has more weak points that Dorian. And he knows how to pose to hide his weak points.
You dont judge by saying, well his back isnt as good, but I like his delts and bi's better, so that means he should win.
