Tim I can’t see the images (work related IS build POS computer) I wanted to share with you one of the neatest ways I’ve seen big poppers used for giant flies. To make this fly a large body of EP, Deer hair, Flash, long feathers, etc, etc, is built up a little behind the eye. Once the body is all built the popper head is reamed out so that it slides over the built up material (sneaky Pete style). Once you have it reamed out it should hide the material build up, then epoxy everything with a thick coat of whatever you use for epoxy. I like Loon hard head.
Fished on a floating line assuming you can cast it on a floating line it would make that V wake that’s so enticing to Muskie. I’ll try to find a picture of what I’m trying to describe. The one I saw was about 12” long.
