I think with flow, focusing on the choreo can become a distraction. While there are some combos that give one another such a great comparison or transition, could a looser choreography allow for the most fun and flow? I've been told by a dancing coach they could see the moves stamped on my face when I focused but when prompted to let my bag of tricks and moves spill out with the music, I found great energy in the improv. It may never come out the same way twice but that's what makes me feel challenged and excited ;*
