Do damp conditions favour Nadal or Djokovic ?

Rain is forcast for Sunday, officials just said they are hopeful to start on Sunday (despite rumours about a Monday final). Do you think the damp clay will favour Nadal or Djokovic ?

damp ==> lower bounce ==> less topspin effect ==> disfavours nadal

it also makes things slower and i think that favours both players.

overall, in the nadal/djoko match-up damp conditions favour djokovic.
