I love the tungsten bead to take it deep! Nice looking fish killer!

that is very cool, i usually tie the partridge behind the bead, I like this.
the body tubing is very neat stuff, I usually have thread as the underbody, and the color of the thread really changes the color, putting mylar under has to make it attractive, and probably would not change the color of the tubing. What other materials would one use as an underbody for body tubing (I use UTC Vinyl rib)?

The original recipe I saw called for a white thread underbody, which would probably preserve the color of the tubing. Krystal Flash would create a neat effect, too.
