It is a odd question , I don't know if it has been addressed before....
When I was young... The fly was a average size of 12-18 ..., an if one looks at the traditional flies ( mom, Bergman) they were in a average of 8-10 ... Now the flies have gotten so small
20-24 ... Did we do this ? Or is it a evolution thing ? I ask this because I reallyike tying the older traditionAl wets .. I don't catch as many .. As I would the smaller size. Would love to hear theory
