These are two Caddis patterns that incorporate beads in their construction in two different ways.
Rick Fox developed the Radical Caddis utilizing beads on an extended body. Rick is a Pro Staff Member for some of the biggest companies in the business and conducts on-the-water clinics for Scott Fly Rods throughout California.The fly is offered commercially through Umpqua Feather Merchants
In the past several years, it has accounted for many fine Trout in Western waters. Instructions for tying this pattern (tied by Jgoding) may be found HERE.
The instructions for tying this fly (tied by FlySlinger) may be found HERE: This pattern has been featured in two of the top Fly Fishing and Tying Magazines. Greg developed this fly for California waters. I am certain Trout in a number of other locations will pounce on it!!!
