I'm with the twins.
The fascinating thing is that everyone at the moment is refering to Sam and Amanda as "the twins", not as "Sam" and "Amanda". This has some profound consquences:-
1. They are not yet identifiable in their individual rights. This means that the public have just lumped them together. Their individual personalities WILL come through later on. But for now they will merge into the background.
2. They almost certainly will not nominate eachother for eviction.
3. When one of them is evicted, the remaining one will be in a strong position to win. They will suddenly "acquire" a personality as they are not just "one of the twins". This could be manipulated very well by C4.
Bearing all the above in mind, I've backed both of them to win at huge odds, in the knowledge that they have a far better chance than most people realise. Yes I know that they both cant win, but the odds I've got (30/1 on each of them) mean that I've got insurance on both of them and I don't mind losing one stake.
Watch the odds come down over the next few days.......
