Balloon Caddis

I hope you don't have enough of caddis patterns. This time it's a balloon caddis devised by the famous Austrian fly tyer and fisherman, Roman Moser. This fly has two big advantages comparing to other dry flies. One is the floatability and the other one is the color of the foam you can easily follow on the water surface. Except the known materials I used for other caddis patterns, you'll need for this one polycelon ( yellow, fluo green ).
I fish the balloon caddis singly as a searching pattern and has proven itself as a very productive fly. You can fish it in an upstream or downstream dead drift.

Hook:           Gamakatsu F11B size 12-16
Thread:        8/0 yellow or gold
Balloon:       yellow polycelon foam ( 2 mm thick )
Wing:           deer hair / CDC under wing
Abdomen:    antron / fur mix ( olive, brown )
Thorax:        rabbit fur

1.Attache the hook firmly in the vice and run on apply your thread base, then cut a strip of foam to suit the hook size used ( 3 mm / size 14, 4-5 mm / size 12) and secure it to the top of the shank with a couple of firm turns.

2.Build the abdomen with the antron / fur mix and wind it on.

3.As you can see, I have my little CDC obsession and I used it as an under wing again.

4.Now prepare a bunch of deer hair and tie it at the same length as the CDC. Trim off the butts.

5.Bring your thread behind the foam, then split it and make a rabbit hair dubbing rope, build the thorax by winding the rope backwards to the base of your deer hair wing.

6.Fold back the foam thorax cover and secure with a few firm turns of the thread, whip finish, cut the rest of the polycelon as short as possible and apply a drop of head cement on the thread.

7.Voilà this is the fly:
