This side of the pond they would fish your fly with with a spider (soft hackle) hung off that. Either tied to the bend of the hook or "two in the eye". The technique is known as "Klink and Dink" as it was used with a Klinkhammer first, now any dry with a trailing wet or nymph gets called that.

Looking at your flies has given me inspiration to solve a tying problem I've been toying with on and off for some time. I think you might like the result. I'll tie some when I get back from work and show you. In the mean time what size is this beastie? (Ho dear living in Scotland is taking its tole!)

Cheers,
A.
