interchangeable body tube flies
has anybody come across these? they have been pioneered in scandinavia as a result of mistake by a flytyer who did not have detailed instructions for tying loop bottle tubes and 'morrum'[this is a type not a make] tubes. he tied a head onto the fine plastic instead of the metal and the put the metal body behind the head and by chance created the interchangeable body system. it has now been taken a stage further in that the prime mover in all this has had special metal bodies made in a variety of weights and shapes and colours. i did not get much chance to use them last year due to low water but from what i did i am confident they will have a place in the salmon fishers armoury.
