urban, mine is just an attempt to list the richest special events of that period.Its an interesting question, if and how we should evalute those special events. I am generally no friend of these 4 men events, but some like the Pepsi Grand Slam had good competition and high prize money. From the early years of open tennis 1968 and 1969, we could look at the BBC 2 event at Wembley in London. It had not the field of the more famous London pro or later British Covered Court at Wembley, but one of the highest first prize money in those years. And its history reached back to 1964, when it was called Golden Racket.
