Jumbo Jon

Cheech - January, 2018

The Jumbo John is a fly created by a world renowned fly designer named John Barr in Colorado. Similar to the Copper John that he also created, a nice smooth body is created with wire, and it can be tied in a wide variety of colors. We chose to tie it in kind of the classic copper color and made some slight alterations on the fly to make it have even more movement in the water. There are rubber legs for tails, I used AZ synthetic dubbing for the thorax, and I opted to use two different sizes of wire (medium and brassie) to create kind of a bumpy look. This is a great fly if you need an anchor for you nymph rig that have very few materials that will impede quick sinking. Change up the colors of wire, bead, and about everything else on this fly to make it your own special sauce!
