I sure as hell do have an argument , Ronnie in terms of size beats Dorian , in terms of sidehead shape and development , Dorian has him beat , and density , please !! and what really matters who has the better sidetricep shot and thats Dorian bar none !! so from that stand point you have no argument !! 
Look at his long head! Ironic how his 'long head' is shorter than the lateral head!

So we both agree that Ronnie's triceps absolutely dwarf Dorian's triceps. Good.
I already acknowledged that Dorian's lateral head has a superior shape to Ronnie.
Ronnie's lateral head is riddled with cross striations, Dorian has none. The genetic inferiority of Dorian's longhead serves to make his lateral head look far more impressive than it really is.
The sidetricep shot is an entirely different debate, one that I will soon enter, but I first want to focus specifically on the triceps.
