My word, it's been quite a while since I last posted!Anyway, missed season 9 although I hope to catch up with it some time.
However I did see season 8, not being a Survivor fan (it only lasted one season over here) I hadn't seen Roberto and Amber before, in much the same way as I hadn't seen Alison before.
They seemed to have a small advantage over the other teams because some people recognised them and were willing to help. However I would say that they had no bigger advantage than any of the Barbie teams have had with their looks.
As racers, apart from sprinting away from the diving roadblock, they were very good. They managed to wind other teams up in a way that no other team seems to have managed, and the underhandedness that they^H^H^H^H Roberto seemed to be prepared to undertake was good to watch.
I appreciate that reality show watchers may well be fed up with them appearing on their 5th show, however as someone who has only seen them once before it works for me!
