I don't see Murray winning Rome. Fed could win Madrid but I'd pick Djokovic and Nadal for Rome. You really think Nadal won't win any of these?
MC - Djokovic
Madrid - Djokovic (maybe Federer)
Rome - Nadal
RG - Djokovic or Nadal.
How to clarky - work out most or only realistic outcome, claim the opposite
Federer, Djokovic, Delpo fan (also like Nalbandian, Dimitrov, Tsonga)
