Hi
red swanundaze ugly is tied with bodyglas (number 17) a Traun River product, the Rudy Heger company . bodyglass is available in many colours and it is stretchable in boiled water.
Some people use it only in nymphs but you must try clear bodyglass rib over dubbing, very nice bodies in 12 14 dry flies
vinyl rib or similar are also good , but those circular tubes that kids use are not good, because when tied give a flat profile. much better if it has a tunnel shape
sorry bad english
