Fly Tying The Unsinkable Dry Fly 

I saw this for the first time around 6 years ago, it looked a fair bit different to this one back then, but it evolved.
I like it, it works, not always but often, I love it as a replacement for a FAB on the washing line.
One tip, tie it on using a loop knot, it's a b***** for spinning on thin tippet!
