Daulton was a through and through champion, in every single game he played. He was not a bank specialist only. He mostly quit pool early to become a promoter in the SouthEast, and then basically played one tournament per year (the DCC), for the next 20 years.
The knowledge of any game can't be learned in a book or video, IMO, especially banks. So while yes, the knowledge is out there, for it to be "learned", It must be played. Today, the only banks game in town is the DCC. So Fedor's only competition is 9 ball players like himself, who play banks once per year at DCC.
The past 10 or so years all the Banks specialist have gotten old, and the best general cueists have won.
Daulton was one of the best cueists, IMO, and also a bank specialist. I think if 21 yr old Daulton played today's Fedor in Banks, Daulton would win. If they played a race to 7 every day for a year, Fedor might become the favorite around the 6 month mark.
