To me, Tess is representative of the autocutie generation. She is a beautiful woman, but without the autocue to rely on, she comes unstuck. When thrown a curve ball, such as when Ricky Groves made the comment about Ant and Dec, she does not know how to react, and seems terrified that someone has crossed the party line or diverted from the script. I'm not a fan of Brucie anymore, but at least he reacts to off-the-cuff remarks with a degree of spontaneity and honesty.
I agree that Claudia would be better than Tess, but that wouldn't be difficult. I fear that her kooky ways would irritate the BBC1 audience after a while. I think Gabby Logan would be better. She's proving herself to have a good sense of humour on Final Score with her handling of the male panel, and is showing that she can adapt to the pace of a fast-moving show.
