I use one that is almost identical to the one that Gillie posted. The white and purple. They work great on the Catt., lower Niagara and most of the Ontario tribs. I also like the Picasse if the water is low and clear.
Scored well with your "Brown Trout Weamer" this past weekend. The water was very cold in the trib I fished (high 30's) but they still took it well. Finally got a chance to tie some up and fish them. Just the standard version, haven't put them on tubes yet.
