I disagree that ToC and Wimbledon 1967 were the best ever pro tournaments.
Wembley and French Pro had often as strong fields and in several years had 16 participants. I agree that ToC and Wimbledon 1967 were first-class events.
Why do you always denigrate Wembley and French Pro?
I don't give ToC and Wim. 1967 a pro GS status because they were played only a few times and once respectively.
The Masters in the late 1950s and in 1964 had as tough participation.
