Okay, well I'm a pretty big fan of Lee, and he does have some insane arms. For his height maybe THE most insane. I just think that in sheer impressiveness Ronnie's are a good few inches bigger, which I know isn't the most important thing, but they are also noticeably harder and considerably more detailed.
Ron's tris were once excellent, Lee's might fade too when he's 43! Forearms is Lee no contest, but Ronnie's are ungodly, just with thinner wrists, which if anything adds the impression of more shape.
In the front double bi Ron's tris have superior detail and separation also. In the 2000 pics the separation is very noticeable. Not to take away from Lee though as obviously he reads these boards and I want him to like me, lol.
