I tied a bunch of these for steelies on Ontario tribs. Used them one day in high water conditions and hooked a big male that made me look silly. Went straight downstream and shook it free like it was a joke to him. Landed a nice little brown and a nice little steelie though later that day out of the chocolate milk I was fishing in.
I don't know if this will come up as a link. Cut and paste if not.

Easy to tie and they look like organic tissue when wet.
