just kidding with you bro. no offense.. sure this is your opinion..
actually ronnie's FLS IMO is not one of the best at all!!.. from the front you cant say how great his lats are.. they dont look full and round as dorian's or even lee haney's.. also his abs looks bad in this pose then finally as you said he has no calves..
shawn is great but is too small to be the best ever especially there are others who are bigger and more impressive and still as complete as shawn or even more complete than him!!.. also shawn's high calves take some from your mentioned poses!..
Its ok, I wasn't offended. Everyone is entitled to their own opinion, if you think Nasser is the best ever, that's great.
What I liked about Ronnie's FLS (in 98-99) is the great taper he had, small waist, wide lats, etc. His abs and calves were a big flaw as you say though. I don't even consider Dorian because even though his lats were great, what about the rest of his bodyparts in that pose? Not so good.
Shawn wasn't as big as Nasser, but he was more complete (in my opinion) and he also hit the side chest pose better.
I'm not a big fan of the "mass monsters" anyway, but I'll say that Nasser was one of the few that actually looked great.
