No, the only part I have with HMC is that I live too close to it. The 'death moth' sometimes wakes me up. Sorry, very sick inside joke.
Concerning listing dates and times I sat with Joe at his clinics. I can't remember what I ate for lunch on Wednesday! Suffice it to say that Mr. H. regularly gives clinics at various locations and I've sat through at least 3 or 4. My son has fished with him.
The man "can cast" and you're right - presentation is paramount to catching fish - regardless of fly used.
As to his fly box, son #1 reports that they are "just like the book". Look like bugs, not like showcase flies meant to catch tourist fly fishers.
Mr. H. is a down to earth guy and his fishing equipment and flies reflect that.
My two year study required that I keep detailed notes of my flies and fish caught, and it didn't surprise me that I carry about 500 flies too many when I go out.
