So basically, you would want to convert masters into slams, and have 8 slams or something like that?
Kind of yes. They wouldnt be grand slams as such, as they would be masters events run by the ATP.
All im saying is what gets people interested in tennis is the majors and the format of the slams - the drama of best of 5 sets, 128 draw which lets people with a low ranking have there day e.g. Rosel against Nadal, played over 2 weeks (so it gives many people the chance to go along and watch atleast 1 day), mens and womens tennis along with doubles.
At the moment the top players play 15+ events over 10 months, yet only the 4 majors and maybe the end of year cup, really draws people's attention into the game.
In the calendar I suggested, the top players would only be required to play 8 events a year which isnt a lot. Maybe having s South African masters wouldnt be financially viable though.
