WCS is a hybrid dance - lots of people who dance it come from another dance. Lindy, shag, ballroom, salsa, whatever. I did a couple of years of Lindy, ballroom and salsa before I settled on WCS. As such, stuff shows up in my WCS that comes from the other dances that I learned. However, my partner connection and my movement was developed over the course of many years of going to conventions and social dancing until my feet went numb. I initially learned WCS in a ballroom according to a syllabus. I also wince noticeably when I compare those days with how I dance now; the form I was taught in ballrooms is a pale shadow of what's danced on the circuit. The main difference is in the connection - it feels more organic than a ballroom lead.
