Like low water flies for salmon
Pit,
It's like the low water flies for salmon. If you want a small fly, but want a sturdy hook, you can simply tie a smaller fly on a hook that was originally meant for a larger size fly. It will appear smaller.
I used these flies for sea trout in the autumn, where a small fly is often a key to success, but where a hook in size 12 or 14 might be just a bit too small to hold the fish.

Thx for these red tag variations
Hello Martin, thx for these red tag variations. I love this red tag a lot; but why fixing such a little red tag on such a large hook? What's the reason and what kind of fish do you aim at?

Red Tag is not a Woolly Worm
David,
I don't think the Red Tag is a Woolly Worm or anything near it. It's a body hackled fly in this variation, but based on an old UK wet and dry fly pattern and not tied in the Woolly Worm tradition at all. Especially not in this "low water" version.
And likening the Copper Bully with its one material to a fly with, 6-7 materials, wings, tail, rib and more is also taking the term variation to its limit in my view.
Just my two cents...
Martin

The flies your talking about are called wolly worms in the U.S. all shapes and sizes can be tied they work great from large size # 4 down to size # 14 weighted or not ribbed with wire or tinsel the skies the limit.You also talk about the copper bully,I tie a varyation called the copper demon the pattern is as follows hook 2 or 3 xl (mustad 9762 or 9761) # 14 - 4 hot orange 6/0 thread,hot orange marabou tail copper wire rib,copper tinsel body,hot orange hackle three turns,hot orange marabou wing with pearl krystal flash mixed in,caught everything from panfish to salmon,keep up the good article's enjoy sharing ideas and information.remember keep the fur and feathers flying.
