Just to add to my earlier post, this one I'll make more detailed:
Artem - 2 series. Won 1, semis in the other. Praised for innovative choreography, but sometimes goes a little too far out there. He likes his props. Not the most encouraging of pros so would be interesting to see how he does with an older or below-average celeb before I can really judge.
Aliona - 3 series. Out week 3 in the first, came 2nd in number 2 and has reached the final in number 3. Pretty good record so far. Innovative choreography again, but less praised and criticised for not putting in enough content on occasion. Had an over-abundance of props last series but has used them sparingly this year. Would like to see her with an "Anita" style celeb.
Kristina - 4 series. Out in 7th place after withdrawing in first series, followed by a week 5 exit in her second, first out in her 3rd series, has made it to the final in her fourth - bit of a mixed bag. Did some great comedy routines with John Sergeant, and has worked the camp factor with Jason in this one, although has been criticised before for her Latin choreography being too disco-y. Has come across as being a bit "desperate".
Pasha - 1 series. Has made it to the final. So far, so good. Has given his partner tons of content in each routine. Has used a fair amount of props though. Need to see him with a less able celeb to judge.
Brendan - 9 series. Won the first, went out week 5 in the second, week 4 in the third, week 8 in the fourth, finished in 6th place after withdrawing in the fifth series, finished 3rd in series 6, went out week 6 in the seventh, week 7 in the eighth, and for series 9 he went out officially in week 6 (although also went out week 9 after replacing Robin for one week). Mixed fortunes although has generally got at least halfway every series. Not the flashiest pro in terms of choreography, but tailors it to his partner very well. Can work with any ability level.
Robin - 2 series. Has finished 7th in both (week 9). Pretty good considering he had "older" women as partners. Seems very encouraging with his partners. Usually quite understated with choreography, but can camp it up when needed. Has started to use more props this series. Want to see him with a talented celeb next series.
Natalie - 3 series. Finished 2nd in her first series, made it to the semis in her second, and went out week 7 in her third. Very much praised for her choreography, which she is able to tailor to her celeb really well. Not averse to using props. Can work with any ability of celeb.
Flavia - 6 series. Withdrew after week 1 in her first, finished 2nd in her second, went out week 1 in her third, week 8 in her fourth, week 6 in her fifth, and week 8 in her 6th. Mixed fortunes but relatively, decent. Can do comedy routines very well, can tailor choreography to celeb very well. Unfortunately think she'll get a duffer next year.
Vincent - 6 series. Finished 4th in his first, went out week 2 in his second, finished 2nd in his third, finished 5th in his fourth, went out week 8 in his fifth, and was first out in his sixth. Some bad finishes but generally gets at least halfway. Understated choreography, can work with any celeb. Difficult to do comedy routines.
Anton - 9 series. Finished 3rd in his first, went out week 3 in his second, finished 5th in his third, went out week 5 in his fourth, week 7 in his fifth, week 2 in his sixth, finished 4th in his seventh, finished 6th in his eighth, went out week 5 in his ninth. Mixed fortunes but some good finishes there. Not renowned for his Latin. The King of the Comedy Routines. Does best with average celebs.
Erin - 9 series. Finished 4th in her first, 3rd in her second, 2nd in her third, went out week 7 in her fourth, week 3 in her fifth, finished 4th in her sixth, went out week 10 in her seventh, week 4 in her eighth, and out third in her ninth. Some very good finishes and she usually gets quite far with her celebs. Again, not renowned for her Latin, doesn't go for comedy routines with her less able celebs. Can work with celebs of any ability.
Katya - 3 series. Went out week 9 in her first, got to the semis in her second, and was out second in her third. Has generally taken less able celebs quite far. Cannot comment on choreography until she has a talented celeb. Hasn't used many props so far.
James - 6 series. Went out week 4 in his first, week 4 in his second, week 9 in his third, week 7 in his fourth, finished 3rd in his fifth, and got to the semis in his sixth. Generally gets at least halfway. Hasn't always got on with his celebs, suffered a few shock exits. Not averse to using props.
Ola - 6 series. Went out week 3 in her first, week 9 in her second, week 7 in her third, won her fourth, went out week 3 in her fifth, and finished 6th in her sixth. Known for the "starfish and posing" Latin choreography, and the catsuit. Mixed bag of results. Doesn't use many props.
