Beautiful piece of fly tying. Always nice to see some quality Ostrich here as well. My usual comment re classics is to try and tie them as they all did back then? That is to say, use the left fibres for the right hand side and right fibres for the left as you’re not battling against the natural flow of the wing fibres?
That said re Hardy, there may well be examples that were tied this way before World War Two perhaps?
I switch between the two methods Andrew. If I want a better edge on the wing for a display fly, I will tie it "tips up". If I am tying a classic fly for fishing with, or just for a more vintage look, I will tie "tips down".
