I am still using Pat Cohen's Carp Dub, but after playing around with some other ideas I have decided to ditch the articulation. Instead I am using a short rabbit strip pierced at the hook and tied in behind the eyes. The cool trick is that I am putting the rabbit strip on upside down so that it pushes the rabbit fur and the Dubbing shag against each other and flattening the profile of the fly. It gives the same laterally flattened profile as the original concept, takes about 1/3rd the time to tie and has BETTER action under water.
Here is a picture:
And here is some bathtub video of the new version:
I think this will probably be the version that goes out for the swap.
