The "B Dun" PMD

[Byron haugh]

This is a size 18 PMD I have named the "B Dun". It was inspired by the "Improved F Fly" shown by Hans Weilenmann here.

There you go, Byron - it has a name.

Now for the $1M question - what stops it from flipping on its side every time it lands? Have you tried?

The tails are splayed, which I think will provide stability. The underneath fold of CDC should also provide stability as it will ride quite low in the water.
Will photo it from above.

You think it will not float "upright"?
I gave it the "bowl of water test" which is not like testing in the stream, but will let you know...............

Wasn't it always "The $64,000 question"? Inflation that high?

[Byron haugh]

What do you think Hans?

[Hans Weilenmann]

What do you think Hans?

I think you are absolutely correct, Byron, on the inflation being too high

And the upright floatation?

I notice in Davie McPhail's version of the F-Fly which he calls the F-Fly CDC Snowshoe Dun fly, he has tail fibers on his fly. Your pattern, and the original F-Fly, are "without tails". Is it not a dun? More of a caddis pattern?

*chuckle* that is for you to establish, and report back on, m'friend.

I tie mine these days on a curved hook, so that the wing lies flush in the film and the abdomen angles down - more the posture of an emerger. Marjan Fratnik's original, with its thread body, will ride similar even though it was tied on a straight shank hook.

You would have to ask Davie direct how he views his version.

I know what Davie's imitates. It imitates a dun.
I am asking about the Improved F fly. I have read it may imitate a Caddis or a midge. No tail/shuck and no thorax. Looks more like an emerging Caddis, however, would it not have a trailing shuck?

....and what were the results of the bowl of water test?

[Byron haugh]

It passed the bowl test with flying colors. Not the true test, as I said, that will come when I fish it in June.
I think Hans may not have realized that the fly has splayed tails.
