Play offs would work for me too. Mens let's have Smeets, Jones .A, Sirianni and Tomic. Womens let's have Stosur, Dokic, Molik and Wheeler.
A few things wrong with this idea
1. Its too late to hold it as those players are entered in tournaments from now until the French Open Qualifying.
2. Tomic is playing junior Roland Garros this year and would be very hard for him to play both events considering he has the chance to win the junior grand slam this year.
3. Smeets, Jones and Sirianni are all out of form and likely first round losers.
I say lets go with Carsten Ball give him a go, hes in form.
