So the tour ain't been blessed with the greatest of conditions so far this year and, going from previous years' performances, the Billabong Rio Pro is unlikely to deliver a whole lot better than Bells, Margaret or Snapper surf-wise. But everyone knows Brazil is all about the heated rivalries between the home favourites and the rest on tour, and the entertaining online judging banter that so often follows.

If we break the men and women's tour down into nationalities (including wildcards), they'll be 9 Brazilians, 12 Australians, 4 Americans, 3 Hawaiians and 3 Euros. A fairly level mix that should deliver plenty of competition! Here's what the heat draw looks like right now:
