"Tag nymphs are certainly not new to fly fishing. However, in my opinion, they are highly underused and under-appreciated in the USA.
I was first introduced to them in Tasmania back in 2007. Our guide showed us a few dry flies and a couple of nymphs. One of them was a tag nymph with a peacock body and a soft hackle.
I of course had to tinker with it. So I switched a few materials to my liking that night at the vise and the Blow Torch was born." - Devin Olson
