From the point of view of someone with no dance or performance skills, my choices would be:
1. Robin
His partners do well in the competition, with no drama or histrionics on his part. The only problem would be that I don't think I'd be a match for him height- or build-wise.
2. Pasha
He seems like the calm and patient type (and I'd need someone very, very patient). My issue with him, though, would be that he seems to put a lot of content into his dances regardless of his partner's ability.
3. Kevin
He also seems lovely, and he's the right height for me. I'm quite introverted, so I'm not sure if his enthusiasm would bring me out of my shell a bit or make me retreat even further. I'd be interested to find out, though... He also seems quite forgiving of footwork mistakes (good!) but relies quite heavily on the "performance" aspect of the dance (bad for me!)
