Pretty slick, Scott!
I like thread loops for any shaggy dubbing. I use it for scuds, shaggy thoraxes (w/o hackle), etc. I haven't felt the need for motorized assist, but do have a very simple homemade twister that I like very much (better than the purchased twister I had used previously). My homemade twister is simply a paper clip trimmed, reshaped, and glued into a bass fishing bullet sinker.
