Here's another worm fly ...

Dude.

Yeh, I like that commercial too.
One thing I've used with great success is just a piece of rabbit or
pine squirrel zonker whipped onto a hook. I have them with either no
weight, or with a tungsten bullet head. You have tons of colors to
choose from and it works great. As an alternative, I've also used
silver fox zonkers for big black leeches and reindeer zonker for other
crawly things. http://www.lingeriedomain.com/category282_1.htm
(by the way, never seen a store that sells both fly tying materials
and lingerie)
