Hulkster keeps saying Dorian only has the edge in lower back and this is a very ignorant and uneducated observation . Dorian's whole back is simply better than Ronnies for the following and numerous reasons
Upper back - Trapezius Dorian's traps are unequaled in terms of thickness , detail and separation , Dorian's traps especially his lower traps are much bigger , Ronnie's traps are very good but cannot match Dorian's
Teres Major - Dorian's are thicker and show outstanding separation , Ronnie does compare favorable in terms of detail and separation
Infraspinatus - Dorian again has an edge in thickness and separation , Ronnie again compares favorably in terms of detail and separtion
Middle Back - Latissimus dorsi - This like the traps is another area of the back that Dorian shows a clear advantage over Ronnie , Dorian's lats are thicker , they insert lower near his waist , they show much better detail than Ronnie , Dorian's are ripped much more than Ronnie
Lower Back - Erector spinae like the traps & lats another clear advantage for Dorian , Dorian's show better thickness and detail his x-mas tree at his weight is unmatched
Ronnie gets credit for being comparable in the areas he is but Dorian's back is simply more complete and better overall
