I think that lefties have an advantage at the Ad side of the court by using the slice serve. I know the righties have the same advantage at the deuce side. But it is better to have this advantage at break points than deuce points, the same applies to your own advantages. The idea is that whenever a righty faces a lefty they should begin their service games at opposite sides. That is, righties could start at 0-0 on the ad side, and lefties should start at the deuce side, so there is no diference. Or the other way, righties at adds on 0-0, and righties at duece like normally. Maybe even switch between sets. This would also make tie breaks more fair. What do you think?
