That was great, but although clever, I think the choreography was much simpler than Kara & Artem's routine. They also had very large spreads to allow their partner to kick inbetween their legs with never a danger of getting tangled and if they did the leg flirting (the cat rubbing thing, which Kara did very well) I missed it.
Kara's routine had more intricate footwork and didnt rely on lifts for impact. I feel Kara could have danced Jennifer's routine blindfolded and while stylish, Artem would have been blasted for playing it safe.
Both great dances - and dancers - though.
