Very nice. I tied something vaguely similar last year - never really got a chance to fish them though. I like your color better. Mine are Adams Grey superfine dubbing.
You using your wing burners on the web wing? Nice!
I spin my dubbing over a mandrel made from a t pin or a straight pin (put pin in vise jaws, wax with dubbing wax, apply 2 microfibbet tails, spin on dubbing, and wet the whole thing down with water base head cement - slide off the pin, curl over your thumb and let dry)
Smallest size I can do of a body is about a size 22 PMD - kinda silly doing anything tinier, but still fun to try!
