I met Jack at one of my fly tying classes in 1985.
They were held at a place called the Fly Tyers Vice, and were instructed by the owner of the shop, Tony Marasco.
Apparently, he and Jack were friends.
And Tony brought him in to speak at one of the classes.
I really enjoyed listening to, and getting to talk to him personally afterward.
One subject that came up there, is something I still remember well to this day.
Tony taught us to wind dry fly hackle with the dull side forward. Said that it floated the fly better.
Jack however, claimed that it was better to to wind them with the bright - or shiny - side forward.
Theythen proceeded to get into some serious bickering about it, that was quite fun to watch.
Leaving me with the conclusion, that it probably doesn't really matter which way you do it.
Although I still to this day, wind the dull side forward - like Tony taught us.
