If I say from week 10 of the competition, when the dancers left are at a high level the bottom two in the dance off should do the same dance so the judges can make a direct comparison, apposed to comparing the dances from the night before.

In the result show of week nine the dance off routine can be drawn by a member of the studio audience, and all couples would have to learn two dances just in case they end up in the bottom two.

If one of the couples have already danced say the (SAMBA) the routine would have to be totally different.

Is this idea over the top, your views would be appreciated.

While, on the surface of things this seems fair. Some dances suit the celebs more. So if the chosen d/off dance is a Salsa for example .. Katie is going to struggle while, if it's ballroom, she's going to excel so it would still play to people's strengths/weaknesses and could be seen as unfair.
Plus there would be the extra burden on them to learn another dance in a schedule already packed. Several other dances infact if they have to avoid the one they're learning that week. How would they know which dance is required?? They won't know who they're up against?

Can't see how it would improve things. Their best opportunity to impress is doing the dance again that they've spent the week learning. It might not suit them but at least they've had a fair crack at learning it.

Sorry if that's garbled! It's early!!

After the debacle over Jamelia being eliminated in the dance-off when she danced better than Peter, I would much rather let the studio audience decide who to save.

A dance-off dance could work if it were one that each of the couples had to rehearse from the start and the demands of the particular dance were fully explained to the audience so they could arrive at a more informed decision about who performed it better on the night.

The major downside to this is that it could become quite repetitive and boring for a light entertainment show
