Was going to do the same thing, Ellen

I thought this site was fantastic.(Hope they will soon translate it all!!) Very detailed research and observations on "rolling" the neck - as a training method.
To all who read it: Don't forget to follow the "Why NOT" link..... more REALLY interesting arguments there!
Another link from there goes to an interesting "biomechanics" page (amongst other things).
Thanks again, Ellen! Very useful!
