LukeB,
Jamie89 and
Cal I think would be loved by the public or someone like
Ammi,
Reece,
Nat or
Niamh would be favourites. Someone like
DrunkerThanMoses would make top 5 easily.
Nicky would have a romance and probably be loved in the house but come about 5th once his galpal goes.
I think somebody like
Lucas or
Jason would be loved on forums but the cat ladies would think their humour is shady. I think
Dezzy would be a more likeable Andy from last year, very intelligent and dry and I think fans would either stan or hate.
I think the first out would be someone like
Cherie,
Livia or
Josy 
just because they are opinionated and don't let anyone get at them...or I would go for clashing with a fan fave over Little Mix or isolating myself
I think
Scott would do really well too it he doesn't get kicked out!
