I don't understand your comment about the hollow hair.
Both flies have wings of Elk or Deer.
The body of Hans's uses CDC and the EHC body is usually some kind
of dubbing, usually palmered and wrapped with wire. Maybe I should have said
that the CDC & Elk will "float as well" as the EHC.
But I still think it fishes better.
Depending on the animal, time of year harvested and area of body the hair comes from, hair ranges from fine (little hollowness) to very coarse (more hollow). Deer tends to be more hollow than elk or coastal deer.
The CDC & Elk I tie uses a sparser wing of elk hock versus my Troth ties. My dubbing is almost always synthetic for drys to avoid absorbing moisture, and I NEVER use wire on a dry fly even when called for. I substitute other materials which add less weight from Kevlar thread to krystalflash and plastic quill. I add sparkle to my dubbing sometimes.
The CDC & Elk provides movement to indicate a live bug which I like. Which is better? Depends on the fish. Both have provided many fish and I wouldn't want to be without either. I've heard raves on Hans' pattern and also that it didn't go ver well by a few. Personally, I really like the pattern because it adds life to the fly and floats well. (Remember NOT to use floatant)
Lastly, remember the fly we were discussing was being tied on a #12 hook! I might tie this size La Fontaine "double-wing" style to get a better float. This style works well in faster water.
