By substituting the feather style wings with hair they often concluded that they had a Trude fly, never stopping to think that what they had was a hairwing variation. Such patterns as the Royal Coachman came to be known as the Royal Trude when it fact it could only be defined as a "Hairwing Royal Coachman." Substituting hair for feathers on all manner of flies took place. In reviewing just the streamers, steelhead and atlantic salmon flies alone one will quickly see where many of their original dressings called from feather wings. There may have been whose who used the idea of "hairwings" prior to Harrison but it is doubtful that any were ever as successful as his original Trude.
