Definition of rolling: moving by turning over and over on an axis
Knowing the rolling X stroke, and using it, rolling doesn't seem to have much to do with it.
So I was trying to think of a name that might be more descriptive of what is actually going on.
First one I thought of was sidewinder........ or to make it more colorful, the yellow bellied sidewinder..........maybe blade exiting the stone stroke (spine staying hone)......things are a little slow here right now .......
