I'm not voting for Pete because his dancing isn't entertaining enough to override the talent factor. Crediting Jowita for the improvements he's made is fair. She's an interesting pro and she's done a good job of maximising potential out of some unlikely celebs (Hamza won me over quickly that year) His personality has grown on me each week though.
I've been voting for Montell because I like her style, her partnership and her journey. I'm glad she made it through the dance off and her dance quality and potential justify remaining in the competition.
I've been voting for Chris because I'm in awe of the way he's been learning to dance with the fairly fundamental adaption of not being able to see what the dances look like. His choreography has not been simplified down and stands up at the level of other contestants. Even on his tougher weeks, he's entertaining.
I tend to vote on the basis of who I'd like to continue in the next week and weighed up against who's more likely to end up in a DO.
