Either Jayne Torvill's or the one with Maria and someone else (is it Kristina? I suppose I could stop being lazy and go check...)

It is Kristina and Maria.

I haven't got either yet, I've ordered the Maria and Kristina one.

Jayne's one has good reviews on Amazon.

I've got the one with Kristina and Maria, but haven't done it yet. I watched it, and it looks alright, but I won't pass judgement until I've done it.

Planning on doing it later today, so will post a review then.
