the Dorian nuthuggers like to pretend those parts don't exist. 
Oh they exist and Dorian has some clearly better ones as well
Gastrocnemius ( outer head )
Gastrocnemius ( inner head ) 
Soleus 
Tibialis anterior 
Dorian has a clear advantage in shape , size , separation , development & detail 
Rectus abdominis 
Dorian has a clear advantage in shape , separation , development & detail 
Intercostals 
Dorian has the clear advantage in separation , development & detail
Serratus anterior 
Dorian's serratus was always much sharper than Ronnies much more clearly defined 
External obliques 
Another advantage Dorian , Dorian's are thicker but when held tight they show much more development & detail compared to Ronnie 
Sartorius 
Dorian's are clearly better much more developed from top to bottom 
Tensor fasciae latae 
Dorian's are clearly more defined than Ronnies 
Latissimus dorsi 
Dorian's are thicker , they're probably equal in terms of sweep but thats were the buck ends , Dorian's lats are denser , much more developed especially from the back his lower lats are shredded  the whole length 
Forearm Flexors 
Dorian's have better shape , are fuller and denser 
Trapezius 
Dorian by far bigger , thicker , denser better development & detail 
Erector spinae 
Dorian again his lower back is thicker more developed and shows better detail
Triceps 
Dorian has an advantage in terms of shape & development and separation of the long head as well as the lateral head , depending on the year Ronnie's may be bigger but not better 
Now these are just parts that Dorian has a clear edge in and NOT the parts that are a push it now couple the edge with better balance & proportion , better density & thickness , better overall conditioning and it becomes obvious that you guys can try all you may to reduce Dorian down to calves & lower back but he's so much more and has clear advantages in parts & as a whole .
