This weeks Fly Frdiay is from PRO Team member Jim Lees, it's the Cased Caddis Bomb...
A Cased Caddis pattern that lets you decide the weight you want to add to it at the riverbank, for the most part for me that means a 2 gram split shot as I only really need it for fishing in a heavy flow of water. It's up to the angler though, you can add and remove whatever you need just by shotting the line at the back of the fly. Adding the weight at this point also makes sure the fly bounces along the bottom with the hook point up.
To create the tag of line to hold the shot take a length of 10lb Line, I use cheap Fluorocarbon with a diameter of 0.3mm, and make a double overhand knot. Tighten the knot and trim leaving a 5mm tag which you then burn with a lighter until the melted tag end meets the knot. From the knot measure down the line 10-15mm depending on the size of shot you expect to use and bend a right angle into the line. Bind this down on top of the hook shank with your tying thread and superglue in place before adding the lead wire or lead foil to the hook shank.
Hook: Partridge of Redditch Sproat Wet G3AY #8
Thread: Semperfli Nano Silk 12/0 White.
Weight: Lead Wire or two layers of Lead Foil depending on how heavy you want the finished fly. Plus a length of Line to attach shot to at a later time.
Head/Front of Abdomen: Natural latex fixed at the eye and wrapped backwards.
Hackle: Brown Partridge feather tied mostly on the top of the shank.
Body: Dark Hare's Ear or Squirrel dubbing wound on tight, trim any long guard hairs then soak the body with varnish. Make sure you have a dubbed body both sides of the shot line as this will help it stay perpendicular to the hook shank.
