I had read years ago Gunter supposedly sported 23's, which by clear comparison there is utter BS. Ronnies arms there were likely legit 23+ and shredded from every angle, never see the likes of them again in my lifetime IMO. I also believe that, despite todays obvious improvements in juice Arnolds arms were better than Heaths. Put them on Arnolds 70's stack and its not even close, Heath would resemble Samir on a good day.
