Dear Brian,

I'll be interested in seeing the replies to this as well. Marc Pettijean (sp) markets a similar product designed specifically for fly fishing ahead of streamers and leeches, etc. but I have never seen anyone come out in praise of them. I've never seen anyone slam them either, in fact I've never seen anyone speak about them.

Myself, I think they are designed to hook more fishermen than fish, especially the item you linked. I can do all that work with a rubber worm by hand, it's really not difficult to to do.

Best Wishes,
Avalon
