Another new one: the "step across". Like man's spin, or shoulder slide, but raise the L-R arms into an arch and step underneath it.

One thing I noted: Ceroc style is to raise the handhold and step forward under it at normal height. JazzJive style is to keep the handhold closer to normal height and bend at the knees to slide under it. Regardless, what's wrong is bending at the waist to get under - which I end up doing if I don't think about it. Tut.
