I want straight answer, oranges!!
I think Tsonga has an edge ATM, but whether that means much remains to be seen. But I assume you're asking about loyalties. I tried the rational approach just for you, you know the younger one will have more opportunities in the coming years and so on, but it's not really working even ahead of the match, let alone when the action starts. It's a lose-lose situation for me. QF or semi, it would become a win-win, but 3rd round, it's almost as bad as that first round clash with Gasquet at USO.
