I hadn't noticed what you said about the Singles/Doubles... it's just that I hate to see that players ranked below 700 almost never had singles activity (not even in qualies), it feels unrealistic.
I'm thinking about reducing most Futures qualies to just 2 rounds (as it happens in a lot of them in real life). Also, I see that in the game some players from main circuit actually plays in both draws sometimes, this could happen also with low ranked players in Futures, right?
I'll work on this the next days. Once I make it work, I'll upload it in case anyone wants to try it.
BTW, if anyone knows when the 2009 ATP schedule will be complete please let me know, I'm willing to update the entire file... yes, I have a lot of free time...
