Hm ... that circular movement of the casino follower is frequently mentioned, but I'm familiar with version of DQN where she actually moves along 2 sides of triangle, with "edge" when she is doing a tap on 4 (assuming on1 timing), of course that triangle can be more sharp or more rounded, but if it is totally circular, it feels as boring as entirely linear movement of the follower in linear CBL
So this "triangular" version is used in linear salsa as well by part of the dancers, just adjusted to remain in the slot, and if used, doesn't feel that different
