I think what was meant
Was that the flies true form is to be tied on large hooks. I have Bill McMillan's book, and he suggests them be tied on 1/0-5/0 partridge hooks. So, that's the designers method of tying them. BUT, and it's a REALLY BIG BUT. You can tie them anyway you want, and they will catch fish. What Bill's thoughts were was using a floating line in rivers where most guys would be dredging with heavy sinktips and huge bushy flies. This way he has a sparsely tied fly on a heavy hook that sunk it for him (per his book). I understand the method.
I myself, think they look really good smaller sized. But have not had a chance to really use them. Have tied them, but not use them. May give them a shot this winter if my shoulder feels up to it.
Don't think they were knocking you. You tie a super gorgeous fly. I'm always in awe when I see what you bring out. I just think they were bringing up the true intent of the fly in question. At least the intent Bill had when he published his dry line steelheading book. Not sure what he thinks today, since I don't know him.
