Artem - a keeper. Great, innovative choreography; has won it once and brought an arguably averagely talented celeb to the semis.
Aliona - twice in the final is a pretty good record, even if the celebs in question were almost guaranteed to be there from their announcement. While I haven't been a fan of her tango-free tango and jive-free jive, her QS and VW have been lovely and have shown how she can teach technique. Give her someone at best average though to see what she can do.
Brendan - why not? He's shown that he can work with talented partners & difficult partners alike and his more relaxed persona is good. Needs to learn AT though.
Natalie - like Brendan, can work with good partners and less talented ones without resorting to using her partner to dance around. Both of these are worth keeping on the height basis as well.
Pasha - definitely a keeper for me too. His choreography has managed to be both traditional, and yet perfectly pitched for such a young partner, carefully building up her solo work. He has a better understanding of AT than most. Judging by how he has worked with Chelsee, I think he would also work well with older contestants.
Katya - is on tricky ground. While she has got a less talented celeb far, she's never had a good partner to show what she could do. However, she has (co) choreographed the only two pro-dances I've liked and also one of the best dances in SYTYCD, so has shown that she could choreograph like a dream, given the opportunity. I'd love to see her get someone good.
Flavia - has shown that a 'straight' pro can work with a comedy candidate (even though I didn't like many of their dances, I much prefered it as an approach than Anton with Ann last year). I'd love to see her with a good partner again - she has interesting choreography.
Vincent - on slightly difficult ground in that he hasn't had many good partners (I nearly said only one in Louisa Lytton!). Like Flavia, has interesting choreography given the chance, but I think this year he checked out a little early and maybe didn't do himself justice as a teacher/choreographer. Still, what would SCD be without without Vincent/Flavia and their AT showcase?
Kristina - has finally had a good partner, and some of her choreography for him was lovely. She also has had a less talented partner, and showcased him well. I could do without an AT like that again, though.
Robin - stepping on Anton's toes in terms of taking a nervous partner and actually getting something out of them. Possibly deserves someone good.
The two couples in danger:
Anton - his attitude to Latin rubbed off on the only good partner he's really had, leaving Laila a complete Latin-phobe. I think he hinders his partners. I really didn't like his attitude this year of making a comedy out of Nancy, seemingly without her knowledge.
Erin - Ishe is a much stronger partner for her celebs than Anton, but maybe not as much as others. Maybe it is for sentimental reaons, but I'd like to see her back next year.
James - while he partnered Pamela well last year, I do not rate his choreography highly. His ballroom is often dull. He seems to have behaved this year like someone who doesn't expect to be back - the comments on Saturday that Craig only gave a 7 because he didn't like Alex were asinine.
Ola - also not a good choreographer. While she arguably hasn't had someone good to demonstrate good choreography, she had in Robbie someone fit, prepared to put everything out there and showed he might have a sense of rhythm and just used him as a prop to dance around - in comparison to Natalie who eked out credible dances from Audley. This partnership I wouldn't mind not returning.
