Stu,

my arms pumped are just short of 19.5 inches. Triceps are my fastest developing muscle group so im lucky in that department. I do get a lot of pain in all of my joints. I tend to use a lot of strapping on my elbows and knees, and some light strapping on my wrists. If you dont do close grip bench very often it will hurt for a while, but the pain will subside as you get used to it.
