Considering the team France will have, this was definitely the best choice : Llodra will be neutralized, and Fischer or even Koubek can create a surprise as none of the other French players are in-form (even Simon is not happy with his game currently, Chardy is out-of-form and Benneteau comes back from injury)
Fischer is better on clay.
I`m afraid not to agree with you on this one. Gasquet and Simon have a similar level on clay courts to Melzer and are superior to Fischer. (OK, Melzer had a fantastic clay court season last year but just check his former years and you will see that maybe was an exception to the rule as he had a fantastic performance overall in 2010 in hard courts too)
Melzer playing the two singles and the doubles match , Koubek is semi retired. Maybe Melzer-Knowle can have some chances against Llodra - Benneteau
Maybe the indoor condition can help Melzer but overall is not a good panorama for the Austrians.
