Jay,
Did you watch Dave's video? I thought his body, tied this way, provides a very buggy look and not as tight of a dubbing loop effect as I thought it would. I think it is because Dave put the dubbing on the thread very loosely before completing the loop and then twisting. I, personally don't like sliding dubbing into a locked loop. Intend to use this method and how it comes out.
I know Dave has used the Hidy et.al. method of making dubbing "noodles" and putting them on cards for later use. Seems like a bit too much effort to me if the results are pretty much the same.
