I would like to start some discussion on this topic since I have recently tied some of these in colors that I thought would be best. Size 14 scud hooks, using various dubbing and darker thorax, often a gold bead head, a sort of mylar like case or back from a computer hardware anti magnetic package - emits a cool shine, and ribbed with something.

Now - are these effective for eastern (US) trout as well as Czech or Poland trout and grayling?

Do I have to fish them in the standard up stream flip in fast water?

Will they be effective fished as a dead drift nymph?

Your thoughts.

Regards,
paff
