i would say steve booth under category 3, and another well deserving name under that category would be joe thomas, 87 year old op legend--he made a op video that freddy used to sell on his site,maybe he still does.....him and fred were good buddies......joe has played one pocket with everyone from cornbread red to bunny rogoff, to eddie taylor, and he's beaten most of them at one time or another..... i know there are some good op players here, but i would guess most of us would have our hands full playing him, and he's 87 years old--and he ONLY plays one pocket and thats all he's played for at least the last 20-30 years.......if not for him, i doubt there would be so many good op players in toledo/detroit area like there are now.......
